Assume that 75% of people are left-handed. If we select 5 people at random, find the probability of each outcome described below, rounded to four decimal places: a. There are some lefties (≥1) among the 5 people. 0.9990 b. There are exactly 3 lefties in the group. 0.2637 c. There are at least 4 lefties in the group. 0.6328 d. There are no more than 2 lefties in the group. 0.1035 e. How many lefties do you expect? 3.75 f. With what standard deviation?
