15. QUESTION: I have in my pocket ten coins. Nine of them are ordinary coins with equal chances of coming up head and tail when tossed and the tenth has two heads. (a) If I take one of the coins at random from my pocket, what is the probability that it is the coin with two heads ? (b) If I toss the coin and it comes up heads, what is the probability that it is the coin with two heads ? (c) If I toss the coin one further time and it comes up tails, what is the probability that it is one of the nine ordinary coins ?
