Question 1191200
<font color=black size=3>
We'll use the nCr combination formula because order doesn't matter when selecting the cards.


Let's find out how many ways there are to select the four hearts
n = 13 hearts total
r = 4 to select


n C r = (n!)/(r!(n-r)!)
13 C 4 = (13!)/(4!*(13-4)!)
13 C 4 = (13!)/(4!*9!)
13 C 4 = (13*12*11*10*9!)/(4!*9!)
13 C 4 = (13*12*11*10)/(4!)
13 C 4 = (13*12*11*10)/(4*3*2*1)
13 C 4 = (17160)/(24)
13 C 4 = 715


There are 715 ways to pick the four hearts.


Then there are 13C1 = 13 ways to pick the 1 spade since we have 13 spades to pick from and one slot to fill.


The number of five card hands with four hearts and one spade is therefore: 715*13 = <font color=red>9295</font>
