Answer:

option d is correct

20

Explanation:

Formula for permutation
_(n)P_(r) is given by:


_(n)P_(r) = (n!)/((n-r)!)

Given the expression:


_(5)P_(2)

here, n = 5 and r = 2

then;


_(5)P_(2) = (5!)/((5-2)!)


_(5)P_(2) = (5!)/(3!) = (1 \cdot 2 \cdot 3 \cdot 4 \cdot 5)/(1 \cdot 2 \cdot 3)

Simplify:


_(5)P_(2) =20

Therefore, the value we get, 20
