Well since there is no chance that she will purchase both of them then it would be just 1 - .51 - .27 = .22

Answer:

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:

= [tex]0.51+0.27[/tex]

 = [tex]0.78[/tex]

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 :

[tex]1 -\text{Probability that she will buy either car A or Car B}[/tex]

[tex]1 -0.78[/tex]

[tex]0.22[/tex]

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