Use a normal approximation to find the probability of the indicated number of voters. In this case, assume that 178 eligible voters aged 18-24 are randomly selected. Suppose a previous study showed that among eligible voters aged 18-24, 22% of them voted. Probability that exactly 43 voted The probability that exactly 43 of 178 eligible voters voted is (Round to four 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?

40% of consumers believe that cash will be obsolete in the next 20 years. Assume that 6 consumers are randomly selected. Find the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years. The probability is (Round to three decimal places as needed.) ...

Use a normal approximation to find the probability of the indicated number of voters. In this case, assume that 111 eligible voters aged 18-24 are randomly selected. Suppose a previous study showed that among eligible voters aged 18-24, 22% of them voted. Probability that exactly 26 voted The probability that exactly 26 of 111 eligible voters voted is (Round to four decimal places as needed.)

Assume that when adults with smartphones are randomly selected, 56% use them in meetings or classes. If 7 adult smartphone users are randomly selected, find the probability that at least 2 of them use their smartphones in meetings or classes. The probability is: (Round to four decimal places as needed.)

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?

Use a normal approximation to find the probability of the indicated number of voters. In this​ case, assume that 143 eligible voters aged​ 18-24 are randomly selected. Suppose a previous study showed that among eligible voters aged​ 18-24, 22% of them voted. Probability that exactly 33 voted

Assume that when human resource managers are randomly​ selected, 38% say job applicants should follow up within two weeks. If 30 human resource managers are randomly​ selected, find the probability that exactly 23 of them say job applicants should follow up within two weeks. a.The probability is?
