Which of the following is equal to c(10, 3)?
a. c(3, 10)
b. c(10, 7)
c. p(10, 3)

C(10,7)

Step-by-step explanation:

We are given that C(10, 3)

We have to find the which is equal to C(10,3) in given options.

C(10,3)=

By using combination formula:

a.C(3,10)

We have n=3, r=10

C(3,10)=

It is not possible because  n factorial is the product of n natural numbers.

b.C(10,7)

Therefore, C(10,7)=C(10,3)

c.P(10,3)

Therefore, C(10,3)

C(10,7)

the answer is 489
