an aircraft make three trips. the probability that it may arrive late in any trip is 0.35, calculate the probability that it may arrive in time in two successive trips

the three ways it can arrive on time in two successive trips:
on time, on time, on time = .65*.65*.65 = 0.275
on time, on time, late = 0.148
late, on time, on time = 0.148
0.148 +0.148 +0.275 = 0.571.
