Question

The probability that Jack plays guitar on a raining day is 0.6 and on a sunny day is 0.5. The probability that is rains tomorrow is 0.8. Find the probability that Jack will not play guitar tomorrow?
Is it 32%?

Answer 1

.8*.6 + .5(.2) = .48 + .1 = .58
1-.58 = .42

Answer 2

how did you get .1?

Answer 3

.5 (1-.8) = .5 * .2 = .1

probability that it will not rain tomorrow = 1 - probability that it will rain tomorrow
= 1 - .8
