### Question 1

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

**A**

${13/102}$.

**B**

$8/9$.

**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 clubs and 13 hearts in the deck. So 2 such cards can be drawn in 13 × 13 = 169 ways. The probability = 169/1326 = 13/102.

### Question 2

A box contains 82 red balls and an unknown number of blue balls. If the probability of drawing a blue ball is 2 times the probability of drawing a red ball, then how many blue balls are there in the box?

### Question 3

Two players, A and B, play a game. It is known that probability of A's victory is 0.34. What is the probability of B's victory?

### Question 4

A box contains 8 orange, 6 khaki and 2 navy marbles. What is the probability of drawing a marble that is not navy if 2 marbles are drawn out randomly?

**A**

${91/120}$.

**B**

$2/16$.

**C**

$92/120$.

**D**

$96/120$.

**Soln.**

**Ans: a**

Total number of marbles is 16. Combinations of 2 marbles that are possible = ^{16}C_{2} = ${16 × 15}/2$ = 120. Chances of drawing a non-navy ball are ^{14}C_{2} = $(14 × (14 - 1))/2$ = 91. So probability = 91/120 = ${91/120}$.

### Question 5

What is the probability of getting a multiple of 3 when a dice is tossed in the air?
