Answer 2

The answer is option (c) 24

Given problem: The number of people = 4

Number of groups that we need to make = 3  

To find: The ways to arrange 4 people in 3 groups at a time where orders matters

Solution:

The formula we will use for the number ways to arrange 4 people in group of 3 at a time = ⁴P₃  

⇒ ⁴P₃ =  4 × 3 × 2 = 24

Therefore, the number of ways = 24
