Question

What is the value of  100 P 2 ?​

Answer 1

Answer:

The value of 100P2 is 9900.

Step-by-step explanation:

100P2 stands for the number of permutation of 100 different things taken 2 at a time.

We know,

nPr= n!/(n-r)!

So,

100P2= 100!/(100-2)!= 100!/98!

Expanding 100! up to 98! as follow:

=> 100P2= 100*99*98!/98!

=> 100P2= 100*99= 9900 (because 98! cancel each other)
