Answer:

28

Step-by-step explanation:

8C6

= 8! / (6!(8−6)!)

= 8! / 6! 2!

= 8 x 7  x  6! / 6! x 2 x 1

= 56/2

= 28

Answer:

The correct answer is  third option 8C₆  = 28

Step-by-step explanation:

Formula:-

nCr = (n!)/r!(n - r)!

To find the value of 8C₆

By the formula we can write,

8C₆ = 8!/6!(8 - 6)!

 = 8!/6!2!

 = (8 * 7 * 6!)6!2!

 = (8 * 7)/(1 * 2 )

 = 56/2 = 28

Therefore the correct answer is  third option 8C₆  = 28
