    Each sex has an equal 50/50 chance

    (1/2)^5 => 1/32

    Each scenario has a 1/32 chance of occurring. There are 5 scenarios. Therefore, there's a 5/32 chance of having 4 boys and 1 girl in any order

    Probability of having a boy is 1/2 (0.5) - There is only 2 genders

    5 children means 2 boys and 3 girls or 3 girls and 2 boys

    0.5x0.5x0.5x0.5x1 = 0.0625 or 6.25%
