a. 0.78 * 0.91
b. both dead = (1 - .78)(1 - .91)
so at least one alive = 1 - (1 - .78)(1 - .91)
c. her alive * him dead = .91 (1 - .78)
The probability that a 50 year old man will be alive in 10 years is 0.78 , and the probability that his 45 year old wife will be alive is 0.91 . Determine the probability that in 10 years:
a. both will be alive
b. at least one will be alive (HINT: what is the complement to the event that at least one is alive?)
c. only the wife will be alive
