There is the opportunity for a trick question along the lines of: You have tossed a coin 99 times and it has come up heads every time. What do you predict for the next toss? Heads; tails; equally likely.

With the correct answer being 'heads'. Because with a fair coin toss they're equally likely, but! Do you know what the global rate of unfair coins is? I don't, but it isn't zero. Trick coins exist. Even ruling that out, the primary purpose of coins is not equal-probability randomization and I'm pretty sure no one is validating their aerodynamics and/or density to make sure they're fair.

So you modify your previous idea of the probability distribution of the coin toss outcomes, and figure the next toss is more likely to be heads.

Actually that's a fun idea for a Bayesian statistics exploration — what does your posterior distribution do as you accumulate more and more results from what is in fact a two-head coin?

Mr. Brown always bets a dollar on the number 13 at roulette against the advice of Kind Friend. To help cure Mr. Brown of playing roulette, Kind Friend always bets Brown $20 at even money that Brown will be behind at the end of 36 plays. How is the cure working?

Probability Calculator: A Guide to Understanding and Using This Powerful Tool

How does a standard probability calculator work? 

A standard allcalculators’s  probability calculator is a tool used to calculate the outcome or chance of an event occurring. It works by inputting information about the event in question and using mathematical formulas to specify the probability.

The basic concept behind probability is the idea of relative frequency, where the probability of an event is defined as the number of times the event occurs divided by the total number of trials.

Example:

For example, if you were flipping a coin, the probability of getting heads on any given flip would be 1/2 or 50%. If you were rolling a die, the probability of rolling a six would be 1/6 or approximately 17%.

Probability calculators can determine the probability of various events, such as the probability of drawing a specific card from a deck of cards, the probability of rolling a certain number on a die, or the probability of a coin landing heads or tails.

Some calculators have built-in functions that can perform common probability calculations, such as finding the probability of a union of events (i.e., the probability that one or both events will occur), the probability of an intersection of events (i.e., the probability that both events will occur), or the probability of an event given that another event has occurred (i.e., conditional probability).

Advanced features

In addition to these basic features, some probability calculators include advanced features, such as the ability to perform statistical tests or generate random numbers. These tools can make predictions about future events or simulate real-world scenarios.

Overall, a standard allcalculators’s probability calculator is a valuable tool for anyone working with probabilities, whether a student, researcher or professional in a field that relies on statistical analysis. Using a calculator, you can quickly and accurately determine the probability of various events, which can help you make informed decisions and analyze data more effectively.

How efficiently does the probability calculator work?

The efficiency of a allcalculators’s probability calculator depends on several factors, including the complexity of the calculations being performed, the processor's speed, the amount of memory available, and the algorithms used by the calculator.

For simple calculations, such as determining the probability of a single event, most probability calculators work very quickly and accurately. They can perform these calculations in a matter of seconds and provide results with a high degree of precision.

However, for more complex calculations, such as those involving multiple events or large datasets, the efficiency of a probability calculator can be impacted. In these cases, the calculator may need to perform many calculations, which can take longer and consume more resources.

To optimise the efficiency of a probability calculator, it's important to use a well-designed and optimised calculator for the type of calculations being performed. For example, if you are working with large datasets, use a calculator that is optimised for handling large amounts of data and has algorithms that are optimised for processing complex data.

Another important factor affecting a probability calculator's efficiency is the user's knowledge and understanding of probability and statistics. Users can use the calculator more effectively and efficiently if they understand the underlying principles and concepts.

In general, modern probability calculators are designed to be highly efficient, and they can easily handle a wide range of calculations. Using a well-designed calculator and a good understanding of probability and statistics, you can effectively and efficiently calculate probabilities for various events and make informed decisions based on the results.

look look i know he's the resident asshole everyone hates but listen this motherfucker has the sexiest voice i have ever heard in my entire life (goddAMN BEN MEREDITH'S VOICE) you cannot say that his voice isn't smooth as fuckin butter. the smug asshole. every fanart of him ever portrays him as the cookie cutter tumblr sexyman okay he is THE MAGNUS SEXYMAN. also possessed by a dead guy and served as an avatar of an eldritch horror beyond our comprehension?? sign me the FUCK UP. did i mention he's voiced by BEN FUCKING MEREDITH?

hello yes I am thinking about how presumably during the war there was some level of media coverage of Jedi Deaths, just bc, y'know, obviously.

and how under the empire there is media coverage of Jedi Deaths bc dead traitor terrorists empire rah rah rah!

and how the major difference is under the empire people care. under the empire people notice.

under the empire, a dead Jedi is a front page article, not a one line mention.

#star wars #coats chats #idk im just. thinking about how the galaxy probably pays statistically more attention to the jedi once they're targets #normal things to thibk about. y'know.
