How many different four person committees can be formed from a group of six boys and four girls?
the answer is most assuredly not ten
But is it mentioned that we'll have 2 boys and 2 girls?
It'd be 10c4 according to me.
\(\Large \color{Black}{\Rightarrow _{10}C_{4} = {10! \over (10 - 4)! \times 4!} }\)
and my answer is also wrong, because i thought it was two boys and two girls. wrongo answer is \[\dbinom{10}{4}=\frac{10\times 9\times 8\times 7}{4\times 3\times 2}=10\times 3\times 7\]
Thank you satellite!
