Please help me solve this problem

2. Let X be the number of COVID patients who show up for a doctor's clinic hours on a particular day. Suppose that the probability distribution of X is P(0) = 0.18, P(1) = 0.21, P(2) = 0.42, P(3) = 0.12, and P(4) = 0.07. Ex. P(2) = means that Required: exactly 2 patients will show up with a probability of 0.42. a. Draw the probability histogram. You may draw first your histogram in a separate sheet of paper, then, take a photo of it and paste below. b. What is the probability that at least two patients show up? Answer C. What is the probability that more than two patients show up? Answer d. What is the probability that between one and three patients, inclusive, show up? Answer e. What is the probability that the doctor will show up?
