Question

Find the probability of getting 2 tails when 3 fair coins are tossed.

Please explain your reply so I understand how to do it. Thanks :)

Answer 1

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
