In five-card poker, a straight consists of five cards with adjacent denominations (e. g., 9 of clubs, 10 of hearts, jack of hearts, queen of spades, and king of clubs). Assuming that aces can be high or low, if you are dealt a five-card hand, what is the probability that it will be a straight with high card 9? (Round your answer to six decimal places.)

Step-by-step explanation:

First we will find the probability of selecting five cards out of pack of cards

Probability of selecting five cards is equal to

On expanding we get

straight high card means five cards with values lesser than but adjacent to it are

there are four card for each number

Hence, probability of choosing five cards is equal to

Probability of getting a straight with high card 9 is equal to

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
