Heehee
P(1 M) = 0.5
P(1 F 1 M) = 0.5 ^2
P(2 F 1 M) = 0.5 ^3
...
E(Male) = 0.5 + 0.5 ^ 2 + 0.5 ^ 3 ... = 1
E(Female) = 0.5 ^ 2 + 2 * 0.5 ^ 3 + 3 * 0.5 ^ 4 = 1
P(1 F 1 M) = 0.5 ^2
P(2 F 1 M) = 0.5 ^3
...
E(Male) = 0.5 + 0.5 ^ 2 + 0.5 ^ 3 ... = 1
E(Female) = 0.5 ^ 2 + 2 * 0.5 ^ 3 + 3 * 0.5 ^ 4 = 1
Yeah!
