Formula for the probability of A and B (dependentevents): p(A and B) = p(A) * p(B|A) The formula is a little more complicated if your events are dependent, that is if the probability of one event effects another. In order to figure these probabilities out, you must find p(B|A...
How to find probability in statistics with a normal distribution Let X and Y be random variables with density functions f and g, respectively, and \xi be a Bernoulli distributed random variable with success probability p, which is independent of X and Y. Compute the probability density function...
How to Find a Sample Size in Statistics A sample is a percentage of the totalpopulationin statistics. You can use the data from asampleto make inferences about a population as a whole. For example, thestandard deviationof a sample can be used to approximate the standard deviation of a popu...
How to Find P-Value? Lesson Summary Frequently Asked Questions What is the p-value in statistics? The p-value (denoted p) for a set of data is the probability that the given data (or something even more unusual) would occur if the hypothesis being tested is not true. How do you fi...
When calculating the probability of an event, use the formula number of favorable outcomes over the number of total outcomes. We can calculate the probability of any event occurring by examining the choices that are available. Let's look at an example to see how simple it is to find the ...
