Answer:
3
Step-by-step explanation:
Total Fairies = 12
Wear White Tutus = 9
So, Wear Pink Tutus = 12 - 9 = 3
Now,
6 have DARK HAIR & WHITE TUTUS, so that means out of 9 with white tutus, 6 of them have dark hair, so the rest would have light hair. How many is that:
9 - 6 = 3
So,
White Tutus = 9
White Tutus (Dark Hair) = 6
White Tutus (Light Hair) = 3
Dakota wants to know how many wear white tutus and have light hair. According to our discussion above, that will be 3 fairies.
