Answer:

True

Explanation:

Given : To select 3 items out of 4 distinct objects, use C(4,3).

To Find: True or false

Solution:

Total items = 4

No. of items to be selected = 3

Since we are not given any sequence of selection .

So, we will use combination.

Formula :
C(n,r)=(n!)/(r!(n-r)!)

So, We will use C(4,3)To select 3 items out of 4 distinct objects

So, To select 3 items out of 4 distinct objects, use C(4,3) is true .
