### Question 1

From a deck of 52 cards two cards are drawn at random. What is the probability that both will be King?

### Question 2

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 = ${91/120}$.
