[QUOTE="statdad, post: 4502839, member: 136993"] First write out the chance that when the trigger is pulled the bullet is not under the hammer: this will also give you the chance the bullet is under the hammer. Now for the first question: if the player is still alive after N trigger pulls, the bullet was not under the hammer any of those times (not the first AND not the second AND ... AND not the Nth): how would you find the probability of that joint event? For the second: if the player is not shot until trigger pull N, that means the first N-1 tries did not have the bullet under the trigger AND the Nth trigger pull did: find the probability of that joint event. As a start to see what happens, you might try working out each solution in the very special case N = 3, just to see how the numbers work out. [/QUOTE]
