You can look at this in a number of ways.\n\nP(Head 1st and Head 2nd) = P(Head 1st)P(Head 2nd) since coin flips are independent.\n= 0.5*0.5\n\nor you can list out all possible outcomes.\n\nHH\nHT\nTH\nTT\n\nSince each of these are equally likely, then the probability is 1/4.\n\nSo anybody above who said that is correct.
