Which of the following statements are true about the events married and college graduate? a) A worker is either married or a college graduate always. b) These events are pairwise disjoint. c) OThese events are both independent and pairwise disjoint d) OThese events are independent events e) O None of these above are true.

Explanation / Answer

Solution:-

e) None of these above are true.

When two events are said to be independent of each other, what this means is that the probability that one event occurs in no way affects the probability of the other event occurring.

But in this case ocuurence of one vent is affecting the other.

A family F of sets is pairwise disjoint if, for every two sets in the family, their intersection is empty.

But in this case the inetrsection of two events is not empty.
