Step-by-step explanation:
there are 2^3=8 possible outcomes after tossing a fair coin fairly 3 times. the eight possible outcomes are : TTT, HTT, THT, TTH, HHT, THH, HHH. exactly 2 of 8 possible outcomes result in 3 of the same faces showing up. they are TTT and HHH. Each has a probability of 1 /8 of happening and since either showing up satisfactorily adresses the criterion for success ,the probability as requested 2*(1/8) = 1/4 = .25 = 25 persent
