There are eight possible outcomes: HHH, HHT, HTT, HTH, TTT, TTH, THH, THT. Of these, 3 contain two tails: HTT, TTH, and THT and the probability of gettin two tails is 3/8. If the question were 'getting at least two tails' then TTT would need to be included for a probability of 4/8 or 0.5 http://wiki.answers.com/Q/What_is_the_probability_of_getting_2_tails_if_3_fair_coins_are_tossed#ixzz1gT8IKjdS
