text: coin flips? what are the chances on two coin flips that both turn up heads? it is 0.25.  you can look at this in a number of ways.  p(head 1st and head 2nd) = p(head 1st)p(head 2nd) since coin flips are independent. = 0.5*0.5  or you can list out all possible outcomes.  hh ht th tt  since each of these are equally likely, then the probability is 1/4.  so anybody above who said that is correct.
