# How do I do this math homework problem? (10 points for best answer!)?

I actually have no clue how to do this. Any help would greatly be appreciated. Thanks!

Suppose we toss two fair dice. Let X = i+j, where i is the outcome of the first die, and j is the outcome of the second die, with i, j ∈ {1, 2, 3, 4, 5, 6}.

Let p(x) = P(X=x) be the probability mass function of X.

p(2) =

p(3) =

p(4) =

p(5) =

p(6) =

p(7) =

p(8) =

p(9) =

p(10) =

p(11) =

p(12) =

This is the very basis of probability, you should review your notes or get a tutor to explain it to you (or the teacher).
