Answer 1

Correct Answer - Option 4 : 55

Concept:-

1. Restricted combination.

2. Any suite has 13 cards in a deck.

Formula:-

nCr for selecting r from n.

Calculation:-

Since Ace is already picked and King is not picked, we need to pick 2 cards from remaining 11 cards of heart.

Number of ways = 11C2 = 55
