A psychologist determined that the number of sessions required to obtain the trust of a new patient is either 1, 2, or 3. Let a be a random variable indicating the number of sessions required to gain the patient's trust. The following probability function has been proposed. f(x)= for a = 1, 2, or 3 %3D a. Consider the required conditions for a discrete probability function, shown below. f(z) > 0 (5.1) Ef(x) = 1 (5.2) Does this probability distribution satisfy equation (5.1)? - Select your answer - Does this probability distribution satisfy equation (5.2)? - Select your answer - b. What is the probability that it takes exactly 2 sessions to gain the patient's trust (to 3 decimals)? c. What is the probability that it takes at least 2 sessions to gain the patient's trust (to 3 decimals)?
