Question

Given: 12% of people are left-handed. a. Consider a simple random sample of 10 people. Calculate the probability that none of these 10 people are left-handed. Also calculate the probability that exactly 2 of these 10 people are left-handed. b. Consider a simple random sample of 100 people. Calculate the approximate probability that 8 or fewer of these 100 people are left-handed
