Thread: Exculusive/non exclusive?

1. A six-sided die is rolled twice. Sketching a sample space to show all the outcomes might be useful. Calculate the following probabilities.
   1. Both rolls result in a sum of 3 or both rolls result in doubles
   2. Both rolls result in a sum of 4 or both rolls result in doubles.
   3. Both rolls result in a sum that is odd or both rolls result in a sum that is even.

a. P(A) + P(B) = 4/72 + 12/72
b. 6/72 +12/72
c. 36/72 + 36/72

Please help

For #2, the outcome set is .

So that probability is .
