Instructions: You can use step-by-step calculator to get the mean and st. deviation associated to a discrete probability distribution.
Mean, or expected value of a binomial distribution is equal to , and the variance is equal to If the number n is rather big, then binominal distribution practically equal to the normal distribution with the expected value np and dispersion npq. This calculator calculates the probability density ...
law of total probability statement proof example law of total probability for two events a and b associated with a sample space s, the sample space can be divided into a set a ∩ b′, a ∩ b, a′ ∩ b, a′ ∩ b′. this set is said to be mutually disjoint or pairwise disjoint...
Entering 0.5 or 1/2 in the calculator and 100 for the number of trials and 50 for "Number of events" we get that the chance of seeing exactly 50 heads is just under 8% while the probability of observing more than 50 is a whopping 46%. While in an infinite number of coin flips a...
This Normal Probability Calculator for Sampling Distributions will compute normal distribution probabilities for sample means X¯, using the population mean, standard deviation and sample size.

The possible outcomes (sample space) for a six-sided die are the numbers one through six. From this list, you can define the two events: Event A: Rolling an even number. Event A would mean rolling {2,4,6}. Event B: Rolling a number greater than four. Event B would mean rolling ...
