Answer 2

Answer with explanation:

Given : A restaurant offers 7 entrees and 11 desserts.

By using the Fundamental Principle of counting , the possible number of choices for two-course meal = Product of number of entrees and desserts.

=
`7*11=77`

Therefore, the number of ways a person can order a two-course meal = 77

30) Given : Number of blouses = 5

Number of skirts = 7

Then again by Fundamental Principle of counting , the possible number of choices for two-piece outfit 5 blouses and 7 skirts will be :-

`5*7=35`

Therefore, the number of ways to choose a two-piece outfit from 5 blouses and 7 skirts = 35
