Question

One card is drawn at random from a pack of 52 cards. Then find the probability that the card is either red card or a king?
1. 5/13
2. 8/13
3. 9/13
4. 7/13

Answer 1

Correct Answer - Option 4 : 7/13

Formula used:

P(E) = (Favorable events)/(Total events)

Calculation

Total red card = 13 heart + 13 diamond = 26

King = 4

Total favorable events = The card is either red card or a king = 26 + 4 – 2 = 28

P(E) = 28/52 = 7/13

∴ The required probability is 7/13
