But to use it, you only need to know the population mean and standard deviation. For any value of x, you can plug in the mean and standard deviation into the formula to find the probability density of the variable taking on that value of x.

It depends on the type of equation i.e. independent events or dependent events.
WebJan 14, 2024 · Sometimes people express the likelihood of events in terms of odds rather than probabilities. The odds of an event occurring are equal to the ratio of favorable outcomes to unfavorable outcomes.

WebIn probability, we say two events are independent if knowing one event occurred doesn't change the probability of the other event. For example, the probability that a fair coin shows "heads" after being flipped is 1/2 1/2. What if we knew the day was Tuesday? Does this change the probability of getting "heads?" Of course not.

WebDec 2, 2010 · Sometimes you can make a practical assumption about the probability of something occurring by considering all the possible outcomes. For example, a coin only has two sides so the probability of it landing on heads (assuming that the coin is "fair") is 1/2. Similarly, a die only has six sides so the probability of it landing on a 4 is 1/6. At other …
