Question

(1). A card is drawn at random from a well shuffled deck of 52 cards. Find the probability of getting neither a red card nor a queen
(2). The HCF and LCM of two numbers are 9 and 360 respectively. If one number is 45 , find the other number.

Answer 1

favorable red cards and queen are 26+2=28 probability =28/52= 7/13

Answer 2

(1) Neither a king nor a queen = 26 + 2 = 28

Probability = 28 / 52 = 7 / 13

(2) HCF × LCM = Product of 2 nos.

9 × 360 = 45 × Other no.

3240 = 45 × x

3240 / 45 = x

72 = x
