52 Cards and you draw 5
- At least one is a 9 and four out of five of the cards belong to the same denomination (2,3,4,5,6,7,8,9,10,J,Q,K,A)
The number of ways to get 5 cards such that at least one is a 9 and four out of five of th cards belong to the same demonation is computed here as:
= Number of ways to select 5 cards such that there is a 9 and there are 4 other cards from same denomination + Number of ways to select all 9s and then fifth card from the remaining 48 cards
Therefore there are 96 ways to get the 5 card hand here.
The probability to get such a hand is computed here as:
= 96 / Total number of 5 card hands possible
Therefore 0.000037 is the required probability here.
