First total possibilities 8 = 2 x 2 x 2 Second Probability of Head 50% (0.5) so 3 coin flips 1.5 = 0.5 + 0.5 + 0.5 That gives you the probability of 1 head so double it for 2 heads is 3 = 1.5 x 2 (Heads) So 0.375 = 3/8 or 37.5% I hope that helps anyone who doesn't want to write out all the possibilities by hand. $\endgroup$ -.
