P sum is 7 or one of the die is 1
WebThe mean of a discrete random variable is defined as E ( X) = ∑ x ∈ X x p ( x) In this case X = { 1, 2, 3, 4, 5, 6 }, so that's where you are getting the multiplication. You can think of the probabilities as weighting the importance of each of these 6 numbers.

Your answer to 2 $A:$ the die rolled is a loaded $\lnot A$: not A or the die rolled is fair $B$ = the sum of 3 values is 4. $P (B A) = 3 (\frac {2} {6}) (\frac {2} {6}) (\frac {1} {6})=\frac {12} {216}$ The only way to do it is if you roll $2$ two's and a one, and the one could show up on any of $3$ rolls.
