Answer 1

Step-by-step explanation:

Total no. of pants(jeans + formal) = 2+2 = 4

total no. of shirts(denim + formal) = 3+4 = 7

Q.18

No. of ways Leela selected outfit = 4 * 7 = 28

so the answer is (d)

Q.19

Formal = shirts * pants

= 3 * 2 = 6

Denim = denim shirt * jeans

= 4 * 2 = 8

Total no. of ways = 6 + 8 = 14

so the answer is (b)
