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.

Forty dash three

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)

Upper P left parenthesis 4 right parenthesis

equalsnothing

(Round to three decimal places as needed.)

(b)

Upper P left parenthesis more than two right parenthesis

equalsnothing

(Round to three decimal places as needed.)

(c)

Upper P left parenthesis at most five right parenthesis

equalsnothing

(Round to three decimal places as needed.)

Which of the events are unusual? Select all that apply.

The event

Upper P left parenthesis 4 right parenthesis

is unusual.

The event

Upper P left parenthesis more than two right parenthesis

is unusual.

The event

Upper P left parenthesis at most five right parenthesis

is unusual.

None of the events are unusual.
