The topic is probability of compound Events.

For this problem, assume that Pr[A ∪B] = 0.6 and Pr[A] = 0.35. (1) What is Pr[B] if A and B are independent events? (2) What is Pr[B] if A and B are disjoint events?

You toss a coin 50 times and find that the outcome was heads 20 times and tails 30. What is the theoretical probability that the next toss will have an outcome of tails?
