    problem involving probabilty

    Along a highway there are 6 rest stops. mike is just as likely to stop at any of the rest stops as he is to pass by it. Find the theoretical probability that mike will stop at 2 or more of the rest stops.

    Can anyone please check my work:
    P(x >= 2) = 1 - [P(0) + P(1)]

    P(0) = 6C0 (0.5)^0 (0.5)^6 = 1/64

    P(1) = 6C1 (0.5)^1(0.5)^5 = 3/3 2

    1- (1/64 + 3/32) = 57/64

    Seems all right to me.

    In future you can use "\choose" command to produce this: 6\choose 0.
