In a family with 4 children, what is the probability of having 1 boy and 3 girls, in any order? (Exclude multiple births and assume all outcomes are equally likely).

  1. Reiny

    your first part is
    (1/2)(1/2)(1/2)(1/2)
    = (1/2)^4
    = 1/16

    2nd part:
    possible outcomes:
    BGGG
    GBGG
    GGBG
    GGGB , so 4 in all
    each one has a prob of 1/16
    so 4/16 or 1/4
