Answer:

0.5904

Step-by-step explanation:

In any 15-minute interval, there is a 20% probability that you will see at least one shooting star. What is the probability that you see at least one shooting star in the period of an hour?

20% probability = 20/100  = 1/5

Probability of Seeing a Star in 15 minutes = 1/5

Probability of no seeing a Star in 15 minutes = 1 - 1/5  = 4/5

probability that you see at least one shooting star in the period of an hour

= 1 - Probability of not seeing any Star in 60 minutes

= 1 - Probability of not seeing any Star in 15 * 4 minutes

= 1 - (4/5)⁴

= 1 - 0.4096

= 0.5904

the probability that you see at least one shooting star in the period of an hour = 0.5904
