assume that 14% of people are left handed. if 7 people are selected at random, find the probability that the first lefty is the fifth person chosen.
so that means that the first 4 are right handed so... 0.86 * 0.86 * 0.86 * 0.86 * 0.14 = 0.077 being that the probability of a right handed person being selected is 0.87 and left handed is 0.14
