Tom and Alice work independently in an attempt to solve a certain problem (i.e. whether one of them solves it does not affect the chances that the other will solve it). The probability that Tom solves the problem is 0.25 and the probability th solves the problem is 0.55. (a) What is the probability that the problem will be solved by at least one person? (b) If you find out later that the problem has been solved by at least one person, what is the conditional probability that Tom solved it?
