Question

learning task 3 direction evaluate each of the following expression and combination​

Answer 1

1. 3! / (2!×(3-2)! = 3! / 2!

= 3 × 2! / 2!

= 3

2. 10! / (4! × (10 - 4) ! ) = 10! / ( 4! × 6!)

= (10×9×8×7×6! ) / (4! × 6!)

= 210

3. 5C3 = 5! / (3! ×( 5-3) !)

= 5! / 3! × 2!

= 10

4. 9C4. = 9! /( 4! ×(9-4)!)

= 9×8×7×6 × 5! / (4! × 5!)

= 126

5. 6C5. = 6! / (5! (6-5) !)

= 6! / 5!

= 6
