An amusement park has 11 roller coasters. In how many ways can you choose 4 of the roller coasters to ride during your visit to

Vadim26 [7]

4!=4*3*2*1=24
11!=11*10*9*8*7*6*5*4*3*2*1=39916800
7!=7*6*5*4*3*2*1=5040
n choose k
how many ways are there to choose k rollercoasters from n choices?

$\left(\begin{array}{ccc}n\\k\end{array}\right)$ = $\frac{n!}{k!(n-k)!}$

$\left(\begin{array}{ccc}11\\4\end{array}\right)$ = $\frac{11!}{4!(11-4)!}$ = $\frac{39916800}{24(7)!}$ = $\frac{39916800}{24(5040)}$ = $\frac{39916800}{120960}$ =330

330 ways
