A national survey found that 42​% of adults ages​ 25-29 had only a cell phone and no landline. Suppose that five 25-29-year-olds are randomly selected.    c) What is the probability that at least one of these adults has only a cell phone and no​ landline? (Round to four decimal places as needed)

Assume that when adults with smartphones are randomly​ selected, 52​% use them in meetings or classes. If 6 adult smartphone users are randomly​ selected, find the probability that at least 4 of them use their smartphones in meetings or classes.

Assume that 9% of people are left-handed. If 4 people are selected at random, find the probability of each outcome described below. ts a) Find the probability that the first lefty is the fourth person chosen. (Round to four decimal places as needed.)

A shipment of 40 inexpensive digital watches, including 9 that are defective, is sent to a department store. The receiving department selects 10 at random for testing and rejects the whole shipment if 1 or more in the sample are found defective. What is the probability that the shipment will be rejected? The probability the shipment will be rejected is (Simplify your answer. Type an integer or decimal rounded to two decimal places as needed.)

Assume that when adults with smartphones are randomly​ selected, 43% use them in meetings or classes. If 14 adult smartphone users are randomly​ selected, find the probability that fewer than 3 of them use their smartphones in meetings or classes. The probability is?

Assume that when adults with smartphones are randomly​ selected, 47​% use them in meetings or classes. If 11 adult smartphone users are randomly​ selected, find the probability that fewer than 4 of them use their smartphones in meetings or classes. The probability is..

Assume that when adults with smartphones are randomly​ selected, 56​% use them in meetings or classes. If 77 adult smartphone users are randomly​ selected, find the probability that exactly 33 of them use their smartphones in meetings or classes. The probability is?
