True or False. To select 3 items out of 4 distinct objects, use C (4,3).

True.

Step-by-step explanation:

C (4, 3) means the number of combinations from 4 items taking 3 at a time. We are selecting 3 distinct items and it doesn't say anything about the order in which they are selected, so we use a combination formula not a permutation (where order does matter).

C (4, 3) = 4! / 3! 1!

= 4*3*2*1 / 3*2*1*1

= 4.

There are 4 ways to select 3 items from 4.
