When two dice are rolled:
List the outcomes for the event that total is less than 5.
Solution
\[\text{ Possible outcomes when two dice are rolled }: \]
\[S = \left\{ \left( 1, 1 \right), \left( 1, 2 \right), \left( 1, 3 \right), \left( 1, 4 \right), \cdots, \left( 6, 5 \right), \left( 6, 6 \right) \right\}\]
\[\text{ Therefore, the number of possible outcomes in the sample space is 36 }. \]
\[\text{ The outcomes for the event that total is less than 5 }: \]
\[B = \left\{ \left( 1, 1 \right), \left( 1, 2 \right), \left( 1, 3 \right), \left( 2, 1 \right), \left( 2, 2 \right), \left( 3, 1 \right) \right\}\]
