Determine the type of probability distribution if any that i

Determine the type of probability distribution (if any) that is appropriate: The probability that a federal income tax return is filled out incorrectly with an error in favor of the taxpayer is 20%. What is the probability that when ten tax returns are randomly selected for an audit, six returns will contain errors favoring the taxpayer?

Select one:

a. Poisson

b. binomial

c. none of these

d. geometric

Solution

Binomial - the prob for favouring taxes is known and n = 10 is known. It is ideal to fit Binomial as the maximum it can take is 10
