Question 389598: if 75 percent of people own a microwave, find the probability that 4 randomly selected people will say they own a microwave. Answer by ewatrrr(24785) (Show Source):
Hi,
Note: The probability of x successes in n trials is:
P = nCx* where p and q are the probabilities of success and failure respectively.
In this case p = .75 & q = .25
nCx =
P(all 4 randomly selected owning a microwave) = (.75)^4 = .3164
