Question

A balanced die is tossed twice. If $A$ is the event that an even number comes up on the first toss, $B$ is the event that an even number comes up on the second toss, and $C$ is the event that both tosses result in the same number, are the events $A, B$, and $C$ (a) pairwise independent; (b) independent?

Step 1

Step 1: Calculate the probabilities of events A, B, and C: - Probability of event A (even number on first toss): 3/6 = 1/2 - Probability of event B (even number on second toss): 3/6 = 1/2 - Probability of event C (same number on both tosses): 6/36 = 1/6 Show more…
