Given : Madan has nine cards from number 2 to 10 of diamond in a shuffled manner.
To find : probability of drawing two cards in sequence from the hand such that each card selected contains a smaller number than the previous one
Solution:
i believe Question would be 2 to 10 of diamond as there are Nine Card
1st card can be from 2 to 10 , probability of each card = 1/9
when it comes 10 then probability of other Smaller card = 8/8
when it comes 9 probability of other Smaller card = 7/8
when it comes 3 probability of other Smaller card = 1/8
when it comes 2 probability of other Smaller card = 0/8
= (1/9) ( 8/8 + 7/8 + ........................+ 1/8)
= (1/9) ( 8 * 9 ) / (2 * 8)
= 1/2
1/2 is the probability that each card selected contains a smaller number than the previous one
