Answer 1

Answer:

120 ways

Step-by-step 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
