  • Renetto where are your answers?

  • #1 potential # of 5 card hands is 52*51*50*49*48=311,875,200.thi­s is derived from 52 different possibilities from 1st card, 2nd card could e any of remaining 51 but can't be the same as the 1st card, 3rd card any of the remaining 50, etc.

    #2 13 cards in a suit,with four suits it would 4*(13*12*11*10*9)=617,760

    #3 if my 1st two calculations are correct, then probability is the answer to #2 divided by answer #1 which is ~ .0009904 or 0.09904%(approximately 1 in 1000 hands you will dealt a flush)

  • incorrect try again

  • ok, what I missed was that the cards could appear in any order, but they would still be the same hand, therefore I should have divided answers one and two by 5! = (5*4*3*2*1)= 120, that makes the new answers..

    #1 2,598,960

    #2 5148

    #3 ~ 0.00198 or 0.198% (approximately 1 in 500 hands will be a flush)

  • this is correct

see all

  • This guy is much cooler than my statistics teacher

  • WTF? your an idoit

  • its actually 1/52 x 1/51 x 1/50 x 1/49 x 1/48 (chances of getting of 10, ace, queen, king and jack) x 1/4 (chances of getting in the same suite)

    which equals to 1/1247500800

  • your not funneh, guy.

  • I'm 11 and I got this i'm using my moms account but for

    1 i got 311,875,200

    2 Dhu there are 4 royal flushs I know cause I play poker

    3 i got 4 over 311,875,200

    I got this by

    answer 1 52 times 51 times 50 times 49 times 48 = 311,875,200

    answer 2 theres four suits in poker so there needs to be for royal flushs

    answer 3 this one was easy there are four royal flushs in the deak so four of those 311875200 hand is four over 311875200

    i'm right face the facts

  • I can see how you might forget to divide by 5! in parts 1 and 2, but even if you do, you should still get the right answer for part 3, since the 5! cancels out. Somehow you managed to mess up the division as well?

  • I meant y/x*
