The

Joint probability of my summiting Mt. Baker in the next two years AND my

publishing a best-selling book in the next two years is .05

.05.

If

the probability of my publishing a best-selling book in the next two years is 10\%

10%, and the probability of my summiting Mt. Baker in the next two years is 30\%

30%, what is the probability that (sadly) in the next two years I will neither

summit Mt. Baker nor publish a best-selling book?
