Question

Perform the indicated calculation.(Round to the nearest thousandth as needed.)

Answer 1

Answer:
`(8C4)/(11C4)=0.212`

Step-by-step explanation:

By definition,

`\text{nCr}=(n!)/((n-r)!r!)`

Using this, we have:

`\begin{gathered} 8C4=(8!)/((8-4)!4!)=(40320)/(576)=70 \\ \\ \\ 11C4=(11!)/((11-4)!4!)=(39916800)/(120960)=330 \\ \\ (8C4)/(11C4)=(70)/(330)=(7)/(33)=0.212 \end{gathered}`
