In a certain town 56% of the households own mutual funds, 39% own individual stocks, and 23% own both. What is the percentage of households that own individual stocks but not mutual funds?

A= the households own mutual funds

B= the household own individual stocks

the household own both

And we know the following probabilities:

For this case we want to find this probability:

households that own individual stocks but not mutual funds

And we can find this with:

And replacing we got:

Step-by-step explanation:

For this problem we can define the following notation:

A= the households own mutual funds

B= the household own individual stocks

the household own both

And we know the following probabilities:

For this case we want to find this probability:

households that own individual stocks but not mutual funds

And we can find this with:

And replacing we got:

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
