\[\huge nCr = \frac{n!}{r!(n-r)!}\] does that help?
anonymous
  • anonymous
ahhhhhhhh!!!!!!!! no
lgbasallote
  • lgbasallote
for example \[3C2 = \frac{3!}{2!(3-2)!}\]
lgbasallote
  • lgbasallote
now does it help?
anonymous
  • anonymous
this is last one then get to go to bed and no ima still lost :(
lgbasallote
  • lgbasallote
here's another one... \[12C10 \implies \frac{12!}{10!(12-10)!} \implies \frac{12!}{10!2!} \implies \frac{12 \times 11 \times \cancel{10!}}{\cancel{10!} 2!} \implies \frac{12 \times 11}{2 \times 1}\] does that help?
anonymous
  • anonymous

okay here's a hint for you \[\small 18! \implies 18 \times 17 \times 16 \times 15 \times 14 \times 13\times 12 \times 11 \times 10 \times 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1\] \[12! \implies 12 \times 11 \times 10 \times 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1\] \[6! \implies 6 \times 5 \times 4 \times 3 \times 2 \times 1\] does that help?
anonymous
  • anonymous
just told me what the !!! do right
lgbasallote
  • lgbasallote
hmm?
lgbasallote
  • lgbasallote
okay here's another hint \[\large \frac{18!}{12! 6!} \implies \frac{18 \times 17 \times 16 \times 15 \times 14 \times 13 \times 12!}{(12!)(6!)}\] does that help more?
