  1. P(2 white or 2 Blue)=P(2 white)+ p(2 blue)= 2/24 + 2/6=5/12

  2. not quite that easy
    you start with 30 socks
    p first blue =6/30
    p second blue = 5/29
    so .2*5/29
    product is p2 blue

    p first white = 24/30
    p second white = 23/29
    product is p 2 white

    so add
    .2*5/29 + 24*23/(29*30)
