Question

The table below gives data on a person's opinion on the death penalty for murder and the person's highest degree. Find the following probabilities: P (Favor and Junior College) P (Bachelor given Oppose) P (High School or Graduate) P (Favor or Less than HS) Brooks Insurance wishes to offer life insurance to men age 60 via the internet. Mortality tables indicate the likelihood of a 60 year old man surviving another year is .98. If the policy is offered to five men age 60: a) What is the probability all five men survive the year? b) What is the probability at least one does not survive?

Explanation / Answer

1) P(favor and junior college) = 67/1385 = 0.0484

P(bachelor give oppose) = P(bachelor and oppose)/P(oppose) = 71/313 = 0.2268

P(high school or graduate) = (732+105)/1385 = 0.6043

P(favor or less than HS) = (1072+54)/1385 = 0.8130

2) a) P(all 5 men survive) = 0.985 = 0.9039

P(at least one does not survive) = 1-0.9039 = 0.0961
