Answer: 0.614
Step-by-step explanation:
First find the probability that he catches the bus in a day.
Probability of catching bus once = 1 - Probability of missing bus
= 1 - 0.15
= 0.85
If he arrives on 3 consecutive days at 7:30 am, the probability he will catch the bus is:
= (P | Day 1) * (P | Day 2) * (P | Day 3)
= 0.85 * 0.85 * 0.85
= 0.614
