... 6. Suppose that in a particular electronic item requiring a single battery, the mean life of the battery is 4 weeks, with a standard deviation of 1 week. The battery is replaced by a new one when it dies, and so on. Assume lifetimes of batteries are independent. What is the probability that more tha ...

... one of A or B occur. Let P be a probability on S. Show that for any two events A and B P (A4B) = P (A) + P (B) − 2P (AB). Solution: Note that A ∪ B = A4B ∪ A · B is a union of mutually exclusive events. Hence we get P (A ∪ B) = P (A4B) + P (A · B ...
