Solution:
- Rita can either wear saree or T-shirt and jeans
- o Number of ways in which She can wear saree = 6C1 = 6
o Number of ways in which she can wear T-shirt and Jeans = 4C1*2C1 = 4*2=8
o Number of ways in which saree or T-shirt and jeans can be selected = 6 + 8 = 14
- o Number of ways in which she can wear Formal shoes = 5C1 = 5
o Number of ways in which she can wear cowboy shoes = 3C1 = 3
o Number of ways in she can wear formal or cowboy boots = 5+3 = 8
