Question

What is the probability that a card drawn at random from a deck of 52 cards is either an ace or a club?
1. 3/17
2. 4/13
3. 5/19
4. 14/17
5. 7/13

Answer 1

Correct Answer - Option 2 : 4/13

CONCEPT:

For 'or' addition function is applied.

FORMULA USED:
P = Favorable outcomes/Total outcomes

CALCULATION:

Number of club cards = 13

Number of aces excluding ace of club = 3

Required P = 13/52 + 3/52

⇒ 16/52

⇒ 4/13

∴ The probability is 4/13.
