Hi all,
May I verify if my thinking is spot on [I've exhausted the ideas, and this is the best I can come up with :O]?
Thank you in advance for any assistance!
If the chances of seeing a meteor outside within an hour are 84%, what is the chance of seeing at least one new meteor outside in 30 minutes?

= 1 -
= 0.6
and
If the probability of observing a car in 20 minutes is 609/625, What is the probability of observing at least one car in five minutes?
P(at least one car in 20 minutes) = 1 - [P(no cars in 5 minutes)]^4
=1 -
