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.
