Question

Ramon is a parking lot attendent. He estimates that 30% of the cars in the lot are sedans 10% are minivans and 20% are SUV's. He designs a simulation.
what is the probabiloty that at least one of the next four cars that enter the lot is a sedan?

A.75%
B.70%
C.85%
D.80%

Answer 1

Then the probability that at least one of the next four cars will be a sedan is 80%, the correct option is D.

How to find the probability that one of the next four cars that enter the lot is a sedan?

So we know that:

• 30% of the cars are sedans.
• 10% of the cars are minivans.
• 20% of the cars are SUV's.

Now we have some simulation results, there are 20 outcomes on the simulation, and the numbers "0, 1, and 2" represent sedans.

Now we need to count how many of the 20 outcomes have one of these numbers, we can see that in 16 of the outcomes at least one of these 3 numbers appear.

Then the probability that at least one of the next four cars will be a sedan is 16 out of 20, or:

16/20  = 0.8

In percentage form, this is 0.8*100% = 80%, so the correct option is D.
