P = Baseball player Barry Bonds broke a major record when he hit 13 home runs in 2001. During that season he was at bat 4.76 times If core of those at bats is randomly selected, find the probability that it is one of the times he hit a home run P = In a recent year, 389 of the 281, 421, 906 people in the United States were struck by lightning.

Explanation / Answer

6. p=135/420000 = 0.0003214

7. p = 73/476 = 0.1533

8. p = 389/281421906 = 0.000001382

9. p = 1/365 = 0.002740

10. p = 16/100 = 0.16
