an ordinary (fair) die is a cube with the numbers 1 through 6 on the sides(represented by painted spots). imagine that such a die is rolled twice in succession and that the face values of the two rolls are added together. the sun is recorded as the outcome of a single trial of a random experiment.
compute the probability of each of the following events:
event:A : the sum is greater than 7
event :B : the sum is divisible by 2 or 6(or both )

Hi!

First, what are all the possible outcomes?

2,3,4,5,6,7,8,9,10,11,and 12

Probably it's higher than 7
There are 5 numbers greater than 7, and 11 numbers total.
7/11

Probability it's divisible by 2 and/or 6.
That would be 2,4,6,8,10,and 12. 6 numbers.
6/11

The answers are

A. 7/11
B. 6/11

Hope this helps! :)
