Please show your work step by step 1)Assume that when adults with smartphones are randomly selected, 65% use them in meetings or classes. If 8 adult smartphone users are randomly selected, find the probability that exactly 2 of them use their smartphones in meetings or classes. The probability is (round to four decimal places) 2) Assume that when adults with smartphones are randomly selected, 59% use them in meetings or classes. If 10 adult smartphone users are randomly selected, find the probability that at least 7 of them uses their smartphones in meetings or classes. The probability is. (round to four decimal places) 3) Assume that when adults with smartphones are randomly selected, 48% use them in meetings or classes. If 10 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 (round to four decimal places)
