Best ResponseYou've already chosen the best response.0Tomas did a nice job, look again, the first blank is for A winning on first flip ______ or 1/2 the second blank is for A winning on the second flip _______ 1/2 times 1/2 the third blank is for A winning on the third flip _______ 1/2 times 1/2 times 1/2 and so on and so on ..... forever .... since it is a geometric series..... These are really challenging questions, using probability and precalculus at the same time .... very challenging and frustrating at times

Best ResponseYou've already chosen the best response.0second blank should be 1/2*1/2*1/2 because first throw: first player get tails second throw: second player MUST get tails too, because we are searching for probability that first wons third throw: first player gets heads and so on
