Question

find the indicated probabilities using the geometric distribution, the poisson distribution, or the binomial distribution. then determine if the events are unusual. use technology to find the probabilities.

sixty-eight percent of parents of children ages 8-14 say they are willing to get a second or part-time job to pay for their childrens college education. you randomly select six parents. find the probability that the number who say they are willing to get a second or part-time job to pay for their childrens college education is (a) exactly two, (b) less than five, and (c) at least two.

(a) p(2) =
(round to three decimal places as needed.)

Explanation:

Identify binomial parameters

$$

$$

Round to three decimal places

$$ P(2) \approx 0.073 $$
