Given:

n=4 and r=3.

To find:

The combinations without repetition are possible if n=4 and r=3.

Solution:

Combination of selecting r item from total n items is:

^nC_r=\dfrac{n!}{r!(n-r)!}

We have n=4 and r=3. By using the above formula, we get

^4C_3=\dfrac{4!}{3!(4-3)!}

^4C_3=\dfrac{4\times 3!}{3!1!}

^4C_3=4

Therefore, the correct option is D.

A high school coach needs to buy new athletic shorts for the 15 members of the basketball team. The coach must spend less than $
AfilCa [17]
If the budget is $200 and he have 15 members then we have divide the two. 200 / 15 = $13.33 per shorts. 15x =< $200. x represents 13.33. So the solution represents the coach may spend up to $13.33 per pair of shorts. If it was even 1 cent more than $13.33 than he wouldn't have enough.So he can spend up to $13.33 or less per pair of shorts.
