    Probability

    Acard player draws 4 cards from a standard pack of 52 cards.
    Find the probability that this results in a card being drawn from each of the 4suits

    Ihave tried these methods.
    Method 1
    (13/52)x (13/51) x (13/50) x (13/49) x 24
    Method 2
    (1/52)x (39/51) x (26/50) x (13/49)
    Whichof these methods is the correct approach?
    Iwould appreciate your comments on this.
    Thankyou.

    Do they give the same answer? NO!
    How can they both be correct.

    Compare this calculation with the one in reply #2.

    I know that method 1(one) and method 2(two) give two different answers but which of the two methods is the correct one to use ?

    Darn, you are hardheaded. Neither of those two is correct.

    See reply #2 for the correct answer.

    Re: Probability

    My fault. I did not see 'this calculation'. I misread it as saying that 'this calculation is correct'.
    Sorry and thanks again for your time and effort.
