Answer:
120 ways
Explanation:
The question here says that there are 5 different robots and we want to arrange them all in a line. How many different ways are thereto arrange them?
---Total number of robots is 5 and since we are dealing with the arrangements without order,then we are talking about combinations
And since the arrangements requires them to be lined up in a single line, we are going to work this out without much stress.
5! ÷ 1! = 5 × 4 × 3 × 2 × 1 ÷ 1
= 120 ways
