Find the indicated probabilities using the geometricdistribution, the Poissondistribution, or the binomial distribution. Then determine if the events are unusual. Ifconvenient, use the appropriate probability table or technology to find the probabilities.

Fifty-six percent of adults say that they have cheated on a test or exam before. You randomly select eight 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)=

nothing

(Round to three decimal places asneeded.)
