Each time you flip a coin, the probability of a given outcome is1/2. This is multiplied by itself every time you repeat the flip. three times: 1/2 * 1/2 * 1/2 = 1/8 decimal: .125
The probability of a fair coin landing heads up is: P(H) = 1/2

The probability of a fair coin landing heads up three times is: P(HHH) = (1/2)3 = 1/8

= 0.125 = 12.5%
One eighth or 12.5%
