Mandee is looking for a new car. she has test-driven two cars but can only purchase one. the probability that she will purchase car a is 0.51, and the probability that she will purchase car b is 0.27. what is the probability that she will not purchase either car a or car b?

a. 0.24
b. 0.22
c. 0.39
d. 0.78

0.22

Step-by-step explanation:

The probability that she will purchase car A is 0.51, and the probability that she will purchase car B is 0.27.

So, the probability the she will purchase either car A or Car B:

=

 =

Since we know that the p+q=1

Where p is a success of event

q is not a success of event

Now we are supposed to find the probability that she will not purchase either car A or car B :

Hence the probability that she will not purchase either car A or car B is 0.22
