Find the indicated probabilities using the geometric distribution, the Poisson d

Question

Find the indicated probabilities using the geometric distribution, the Poisson distribution, or the binomial distribution. Then determine if the events are unusual. If convenient, use the appropriate probability table or technology to find the probabilities. Fifty-nine percent of adults say that they have cheated on a test or exam before. You randomly select seven adults. Find the probability that the number of adults who say that they have cheated on a test or exam before is (a) exactly four, (b) more than two, and (c) at most five. (a) P(4) = (Round to three decimal places as needed.)

Explanation / Answer

a) We will use Binomial distribution, here n = 7 and p =0.59

For P(4)

use excel function

BINOM.DIST(4,7,0.59,FALSE) = 0.292
