For #2, the outcome set is .
So that probability is .
a. P(A) + P(B) = 4/72 + 12/72
- A six-sided die is rolled twice. Sketching a sample space to show all the outcomes might be useful. Calculate the following probabilities.
- Both rolls result in a sum of 3 or both rolls result in doubles
- Both rolls result in a sum of 4 or both rolls result in doubles.
- Both rolls result in a sum that is odd or both rolls result in a sum that is even.
b. 6/72 +12/72
c. 36/72 + 36/72
