Assume that you remove all of the hearts from a normal deck of cards. Now, with this new hearts-only deck, how many possible five-card hands can you draw? (A normal deck of cards has 52 cards, 4 suits, and numbers 2-10, Jack, Queen, King, Ace.)

a. 4,669,920
b. 311,875,200
c. 154,440
d. 6,497,400

Answer:

c

Step-by-step explanation:

The possible way to draw 5 cards hand from set of  hearts-only deck is  15,4440 .

What is permutation?

Permutations are different ways of arranging objects in a definite order. It can also be expressed as the rearrangement of items in a linear order of an already ordered set. The symbol [tex]P_{r} ^{n}[/tex] is used to denote the number of permutations of n distinct objects, taken r at a time.

Formula of permutation

[tex]P_{r} ^{n}[/tex] = [tex]\frac{(n!)}{(n-r)!}[/tex]

According to the question

Remove all of the hearts from a normal deck of cards.

i.e,

Total normal deck of cards = 52

On Removing hearts cards(n) = 13  

Now, with this new hearts-only deck, how many possible five-card hands can you draw .

Card to draw (r)= 5

Applying formula of  permutation

[tex]P_{r} ^{n}[/tex] = [tex]\frac{(n!)}{(n-r)!}[/tex]

n = 13

r = 5

Substituting the values

[tex]P_{r} ^{n}[/tex] = [tex]\frac{(13!)}{(13-5)!}[/tex]

[tex]P_{r} ^{n}[/tex] = [tex]\frac{(13*12*11*10*9*8!)}{(8)!}[/tex]

[tex]P_{r} ^{n}[/tex] = 15,4440

Hence, the possible way to draw 5 cards hand from set of  hearts-only deck is  15,4440 .
