Question: Use the sample space given in Example. Write each of the following events as a set and compute its probability.
Example: Rolling a Pair of Dice
A die is one of a pair of dice. It is a cube with six sides, each containing from one to six dots, called pips. Suppose a blue die and a gray die are rolled together, and the numbers of dots that occur face up on each are recorded. The possible outcomes can be listed as follows, where in each case the die on the left is blue and the one on the right is gray.
The event that the sum of the numbers showing face up is at least 9.
