Hello, so the sum of the numbers on the two guys can either be two, three, four, five, six, seven, eight, nine, ten, eleven or two.
00:28
The two cannot add up to one, obviously.
00:31
The probabilities, as far as far as refuse of this outcome is one over 36, two over 36, four over 36, four over 36, four of 36, 5 over 36, 6 over 36, 5 over 36, 4 over 36, 3 over 36, 2 over 36, and 1 over 36.

So this is our x, and this is our p of x.
01:23
So our ex, expectation is simply sigma x times px.
01:34
So this times this plus this times this plus this times this plus this times this multiply if each outcome and its probability and add it to the next outcome times this probability and on it on and that would give us 2 .5, 2 over 36...
