Question

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

Answer 1

Option (3)

Explanation:

Permutation is defined by the expression,

P(n, r) =
`(n!)/((n-r)!)`

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

P(10, 3) =
`(10!)/((10-3)!)`

=
`(10!)/(7!)`

=
`(10* 9* 8* 7!)/(7!)`

= 10 × 9 × 8

= 720

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