Probability is the event happening divided by the total events

The event that must be happen is Sarah and Janet will drive a red number car.

We have 2 red cars, 3 green cars and 3 blue cars, a total of 8 events

The probability that Sarah will drive a red car is 2/8

Now we have 7 cars left to choose from and 1 of it is a red car.

The probability that Janet will drive a red car is 1/7

Multiply the two probabilities.


(2)/(8)*(1)/(7)=(2)/(56)=0.036

In percentage :

0.036 x 100 = 3.6%

The answer is 3.6%
