Question

30 ISN’T RIGHT!!! Please give me an answer

Answer 1

Answer:

Option (3)

Step-by-step explanation:

Permutation is defined by the expression,

P(n, r) = $\frac{n!}{(n-r)!}$

Therefore, for the value of P(10, 3),

P(10, 3) = $\frac{10!}{(10-3)!}$

            = $\frac{10!}{7!}$

            = $\frac{10\times 9\times 8\times 7!}{7!}$

            = 10 × 9 × 8

            = 720

Therefore, Option (3) will be the correct option.
