We are doing probabilty and if there is a sock draw with 24 socks in there and you want to know the P. of picking 2 white socks. If there are 10 white socks in the draw, how would this work?

  • math 7th grade -

    prob that first sock is white = 10/24
    prob of second sock also white = 9/23

    so prob (2white socks) = (10/24)(9/23) = 15/92

    Thanks
