Question

From a well shuffled standard pack of 52 playing cards, one card is drawn. What is the probability that it is either a red card or black card.

• A. 1
• B. 1/2
• C. 1/8
• D. 1/4

Answer 1

The correct option is A 1

No. of red cards $=$ 26, No. of black card $=$ 26,
No. of total cards $=$ 52

Probability of red card $=\frac{26}{52}$

Probability of black card $=\frac{26}{52}$

Probability of red or black card $=\frac{26}{52}+\frac{26}{52}=1$
