You could have done this much more easily. If you have a full house, the two

a
kind can be one of 13 types of cards. 1/13 = 0.077. 5/7 CEE 202 – Engineering Risk & Uncertainty Spring 2011 (Bond) Homework 2 Combining probabilities 5)(15points) The probability that a male will die before his 66th birthday is 79.3%. The probability that a male will die before his 71st birthday is 71.5%. What is the likelihood that a 65
year
old man will be alive in five years? Hint: What do you know about the 65
year
old man? You already have the knowledge that the man has survived to age 65. This is a conditional probability—the sample space now excludes all the people who died before age 65. If you survive to age 70, then you must also survive to age 65. P(S70 ∩ S65) = 0.715 P(S70  S65) = P(S70 ∩ S65) / P(S65) = 0.7...
