How can I find the following properties of 2 dice thrown? (details inside)
having problem with that, could you please aid?
we throw 2 dice again and again until the first time we obtain the sum of #8# (of both dice, for instance 4 and 4, 6 and 3 etc..).
we mark X as the number of times we got a sum that is not 8.
a)what are the odds we will throw the dice more than 7 times?
b)what is the mean of X?
c)if we know that the dice were thrown at least 2 times, what is P{x=8}?
