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?
${91/120}$.
$2/16$.
$92/120$.
$96/120$.
Ans: a
Total number of marbles is 16. Combinations of 2 marbles that are possible = 16C2 = ${16 × 15}/2$ = 120. Chances of drawing a non-navy ball are 14C2 = $(14 × (14 - 1))/2$ = 91. So probability = 91/120 = ${91/120}$.
