    if its a 6 sided dice the probability is 0, because here is not a 7

    so how would i right this P(6)=1/6 P(7)=0/6 P(6)*P(7)=0/6?

    perhaps it's that you roll two dice, so you can numbers 2-12

    well to get 6, you could have (1 & 5)x2, (2&4)x2, 3&3

    so it is talking about the sum, there is 5 ways to get a sum of 6, and 6 ways to get a sum of 7, so the probability would be 11/36

    So What do i do for P(6) and P(7)

    there are 6 ways to roll one die...the ones that are relevant to us are 1 to 5 for the first die, so 5/6

    the p(6) is 5/36 since there is 5 ways to get a 6 (1 + 5, 5+1, 2+4, 4+2, 3+3) and there are 36 outcomes on 2 die

    there is only one number on the next die that will give us our 6, no matter what we rolled first, so 1/6 for second

  21. anonymous

    so the answer is 5/36?

    so for the 7, all 6 on the first die can give us 7...and only one on the next die so, 6/36 for 7
