Question

ramon is a parking lot attendant. he estimates that 30% of the cars in the lot are sedans, 10% are minivans, and 20% are suvs. he designs a simulation. let 0,1, and 2 represent sedans. let 3 represent minivans. let 4 and 5 represent suvs. let 6,7,8 and 9 represent other cars. the table show the simulation results. what is the probability that at least one of the next four cars the enter the lot is a sedan?

Answer 1

The probability that the nest set of cars that would enter the lot is a sedan is given as 80 percent

How to solve for the probability

The total number of trials can be seen to be 20 in number. The numbers that represents the sedan are 0, 1, 2

Now we would have to count the number of trials in these 20 that have 0, 1, 2

In the table we have 16 of these 0, 1 or 2 numbers

Hence we would have

16 /20

= 0.8

= 80 percent
