Total combination of shirt and pant = 9C1*8C1 = 9*8 = 72

Total combination of 2 specific shirts with 3 specific pants = 2C1*3C1 = 6.

So, answer will be 72 - 6 = 66. option D.

Total combinations without restrictions= 8*9= 72

Combinations of wearing 2 specific shirts with 3 specific pants= 2*3= 6

Combinations with restrictions= 72-6= 66

Total number of combinations without restrictions: Total Number of Shirts AND Total Number of Pants = 8*9 = 72

Restriction: Two Shirts AND Three Pants = 2*3 = 6

Total number of combinations with restrictions: 72 - 6 = 66 (D)

Oh, I don't understand this question. "she doesn't wear 2 specific shirts with 3 specific pants" - it means that she doesn't wear them at the same time? Or she doesn't wear shirt or pant separately?

My answer is that she will have 6C1x6C1 choices. Please explain it to me.
