A distribution is the one where only two outcomes are possible for all the trials

Answer:
Step-by-step explanation:
- When an experiment has only two possible outcomes,…the result is what we call a binomial random variable.…A coin flip can only result in heads and tails.…Eligible voters can either vote or not vote.…A patient can either test positive…or negative for a disease.…These are possible binomial random variables,…provided we have n trials…with a probability of success we call p.…In other words, if we take our coin and flip it four times,…n is equal to four, the number of flips,…p is equal to 0.5, the chance of success,…which either can be heads or tails in this case.…
How 'bout if we take voter turnout?…Let's say there are 5,000 registered voters.…And let's say the probability a registered voter…will actually vote is 60%.…Now, n equals 5,000…and p is equal to 0.6, or 60%.…Let's use binomials to solve a problem.…Suppose an organization has a monthly meeting.…New people attend the meeting each month,…but only 20% end up joining the organization.…
Suppose three people attend this month's meeting,…Tom, Lori, and Fred.…What are the chances one of those three people…
