How to find r in this equation using combination formula C(8,r)=28<br>​
slavikrds [6]

Answer:

r = 2

Step-by-step explanation:

We have the formula of ^nC_r = \frac{n!}{r! (n-r)!}

Now, it is given that ^8C_r = \frac{8!}{r! (8-r)!} = 28 ........ (1)

And we have to find the value of r which satisfy the above equation.

So, r! (8-r)! = \frac{8!}{28} = \frac{40320}{28} = 1440

Now, we have to use the trial method to find the value of r.

For r = 1, 1! (8-1)! = 7! = 5040 \neq 1440

Hence, r can not be 1.

Now, put r = 2, 2! (8-2)! = 2 \times 6! = 1440

Therefore, r = 2 (Answer)
