1. In a study of fatal car accidents, some accidents were attributed to high speed or drunk driving.

- The probability that the fatality was attributed to high speeds was 0.57
- The probability that the fatality was attributed to drunk driving was 0.62
- The probability that high speed and drunk driving caused the accident was 0.41

*Hint: Make a Venn Diagram*

a. What is the probability that a fatal accident will be attributed to high speeds or drunk driving?

b. What is the probability that a fatal accident will be attributed to neither cause?

c. What is the probability that the fatality will be attributed to drunk driving, but not high speeds?

2. A recent poll yielded the following results.

Support the legalization of Marijuana (L) | Support Health-care Reform (H) | Support Stem-cell Research (S) | Total | |
---|---|---|---|---|

Male (M) |
600 | 365 | 535 | 1500 |

Female (F) |
418 | 559 | 523 | 1500 |

Total |
1018 | 924 | 1058 | 3000 |

a. Find $P(M \cup H)$

b. Find $P(L')$

c. Find $P(F \cap S)$
