In a recent survey of 100 women, the following information was gathered.

39 use shampoo A.
42 use shampoo B.
48 use shampoo C.
14 use shampoos A and B.
15 use shampoos A and C.
12 use shampoos B and C.
8 use all three.
Use the figure to answer the question in the problem.

How many are using shampoos A and C, but not B (Region IV)?
1 women

I came up with 15 women is that right

My intepretation:

N = 39 + 48 + 15 = 102.

To determine the number of women using shampoos A and C, but not B (Region IV), we need to follow these steps:

1. Find the total number of women using shampoos A and C. According to the information given, 15 women use shampoos A and C.

2. Determine the number of women using all three shampoos (A, B, and C). From the information, it is given that 8 women use all three shampoos.

3. Subtract the number of women using all three shampoos from the total number of women using shampoos A and C. Therefore, 15 - 8 = 7 women are using shampoos A and C, but not B (Region IV).

So, the correct answer is 7 women, not 1 woman.
