The probability the team rocket will fight is 1/5 or 0.2 since it only fights once in 5 days

Therefore, the probability that it will NOT fight is 1 - 0.2 = 0.8

The probability they will blast off given that they do not fight is 30% or 0.30

Therefore the probability that BOTH events happen is

(0.80)(0.30) = 0.24 = 24%  choice b.
