A bag contains four number blocks

Question

A bag contains 4 number blocks. If you were to pick ONLY THREE blocks from the bag, what are all possible outcomes?

 

Blocks consist of: 8 0 2 5 

Answer 1

The four distinct outcomes are determined by listing original numbers, except one of them. That means there are four ways to choose three, leaving one not chosen. 

 

You do not say whether the order of selection matters. If it does, then this answer must be 4P3 = 24

Otherwise (order does not matter), the answer must be 4C3 = 4.

 

Since significance of order was not explicitly mentioned, four is the best answer.
