Unformatted text preview: i th toss turns up heads, then we say the tosses are independent if the events A i are independent. Suppose we toss a coin repetitively and independently, and let A i be as before. Let us assume that the probability of a heads is p . Let X be the number of the toss at which we rst get a heads. Then X being equal to n is the event A c 1 A c 2 A c n-1 A n . By independence, the probability of this is (1-p ) n-1 p. 4...
