Question
In a study of 420,000 cell phone users in Denmark, it was found that 135 developed cancer. Estimate the probability that a randomly selected cell phone user will develop a cancer. 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. Estimate the probability that a randomly selected person in the United States will be struck by lightning that year. On their first date, Kelly asked Mike to guess the date of her birth, not including the year, What is the probability that Mike will guess correctly? (ignore leap years) P = The 110^th congress of the United States included 84 males Senators and 16 female senators. If one of these Senators is randomly selected, what is the probability that a women is selected? P =
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
