### Question 3

### Question 4

From a deck of 52 cards two cards are drawn at random. What is the probability that both one is a hearts, and the other a Spades?

**A**

${13/102}$.

**B**

$3/7$.

**C**

$14/102$.

**D**

$18/102$.

**Soln.**

**Ans: a**

Number of ways of drawing 2 cards out of 52 = ^{52}C_{2} = $(52 × 51)/2$ = 1326. There are 13 hearts and 13 Spades in the deck. So 2 such cards can be drawn in 13 × 13 = 169 ways. The probability = 169/1326 = 13/102.
