Find the value of 17C3 680 12,376 2,380 54

Answer 1

Answer:

54 because I don't know I can't explain

Answer 2

Answer:

680

Step-by-step explanation:

Using the definition

n$C_{r}$ = $\frac{n!}{r!(n-r)!}$

where n! = n(n - 1)(n - 2)...... × 3 × 2 × 1

17$C_{3}$

= $\frac{17!}{3!(14)!}$

Cancel the multipliers of 14 × 13 ×...... on the numerator with 14! on denominator.

= $\frac{17(16)(15)}{3(2)(1)}$

= $\frac{4080}{6}$

= 680
