Question

Two cards are drawn at random from a deck of 52 cards. If probability that both cards are of red or both are queen is m/n( m,n are coprime integers), find m+n/3

Answer 1

Answer:

92

Step-by-step explanation:

Two cards are drawn at random from a deck of 52 cards.

Total Possible Draw

= 52 * 51

= 2652

Both are Red

= 26 * 25

= 650

Both are Queen

= 4 * 3

Out of 12  Two cases are of Red

So total 650 + 12 - 2 = 660

Probability = 660/2652  = 110/442

= 55/221

m = 55

n = 221

m + n = 55 + 221 = 276

(m+n)/2 = 276/3 = 92
