Question 4 of 11 Points: 10 out of 10In a population, 8% of the males have had a kidney stone. Suppose a medical researcher randomly selects two males.Let X represent the event the first male has had a kidney stone. Let Y represent the event the second male has had a kidney stone. Which of the following is true about the two events?X and Y are disjoint. X and Y are independent. Both (A) and (B) are true. None of the above are true. Good job! The occurrence of X does not affect the probability of Y since the men are randomly selected from a large population. So the events are independent. Also, these two events overlap. If K = had a kidney stone and N = no kidney stone, then KK is a possible outcome. Thus, the two events are disjoint. Besides, recall that if events are independent, they cannot be disjoint.
