    probability(urgent)

    (i) You draw 2 cards from a deck of 52 cards and the return as follow:

    Result
    How much you win
    Blackjack or Double Aces
    $50
    Total is more than 16
    $10
    Done of the above
    - $5

    (Assume the face value of an ace is 11)


    (a) A man rolls a die for 10 times, find the probability that
    (i) he gets 2 sixes, given that he gets 2 fives.
    (ii) he doesn’t get the same number consecutively.

    (i) Besides receive the prize, a visitor who spent more than 2 hours in the casino would receive an envelope with coupon. Coupons in envelopes were numbered 1 to 5, and a set of one of each was required for applying the VIP card. Assume all numbers are equally probable, with one coupon per envelope, how many envelopes on the average were required to apply the VIP card?

    It is not binomial!
    But one could write it as \frac{{10!}}{{3!3!4!}}\left( {\frac{1}{6}} \right)^3 \left( {\frac{1}{6}} \right)^3 \left( {\frac{4}{6}} \right)^4 .
