Question

2. In November of each year, a walk-in clinic allows people to walk in to get a flu shot. Let X be the number of people who come to the clinic for a flu shot on a randomly selected day in November). Suppose X has the following distribution: 2 0 1 2 3 4 5 P(X = 2) 0.3 0.1 0.2 0.1 0.1 0.2

Answer 1

P(X < 4, X > 3) 2. We want P(X<4X > 3) = P(X >3) P(X = 3) + P(X = 4) 0.1 +0.1 0.1 +0.1 +0.2 0.4 -= 0.5;
