Answer:
Option (3)
Step-by-step explanation:
Permutation is defined by the expression,
P(n, r) = [tex]\frac{n!}{(n-r)!}[/tex]
Therefore, for the value of P(10, 3),
P(10, 3) = [tex]\frac{10!}{(10-3)!}[/tex]
= [tex]\frac{10!}{7!}[/tex]
= [tex]\frac{10\times 9\times 8\times 7!}{7!}[/tex]
= 10 × 9 × 8
= 720
Therefore, Option (3) will be the correct option.
