Answers
Given:
Leela decides to select either a formal shirt with a pair of formal pants (not with jeans) or a denim shirt
with a pair of jeans (not with formal pants).
To find:
The total number of ways she can select the outfit now are :
Solution:
From given, we have,
Two types of pants - Jeans and Formal, with 2 choices for each of them - Formal and Denim.
⇒ 3 choices for formals and 4 choices for denims.
∴ The total available choices for shirt = 3 + 4 = 7
Jeans and Formal pants with 2 choices for each of them
⇒ The total available choices of pants = 2 + 2 = 4
a formal shirt with a pair of formal pants
= 3 choices for shirt × 2 choices for formal paint = 3 × 2 = 6
a denim shirt with a pair of jeans
= 4 Choices for shirt × 2 Choices for Jeans = 4 × 2 = 8
∴ The total number of ways she can select the outfit now are 6 + 8 = 14 ways
