12 possible first objects leaves 11 possible second objects leaves 10 possible third objects etc. 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 = 12! / (12 - 8)!

You want to just arrange them: So, the number of ways in which \(r\) objects can be arranged from \(n\) different objects is given by: \[\large \implies ^nC_r\]

\[^12C_8 = \frac{12!}{5! \times 8!} = \frac{12 \times 11 \times 10 \times 9}{5 \times 4 \times 3 \times 2 \times1} = ??\]
