Answer:
60 ways
Explanation:
If we have a total of 5 people, and we have to choose 3 of the 5 people, then you can organize the problem like this:
In the first slot, you have 5 options
_ _ _
5
In the second slot, you have only 4 options since you already picked someone
_ _ _
5 4
In the third slot you have 3 options, since you have already picked two other people
_ _ _
5 4 3
Then you just multiply the numbers, and voila! You have 60 different ways!
You could also organize it with a tree diagram to really see how this idea works. (See attached photo)
