Total number of different ways that the awards can be distributed is; 150 ways.

  • It is clear from the question that the awards and the students are different.
  • Now, each student will receive at least one award.

This means that the five different awards could be separated into;

3 + 1 + 1 awards or 2 + 2 + 1 awards.

  • Now, for one person to get 3 awards and the other 2 people to get one award each, the number of ways is calculated as;

       ⁵C₃ × 3! = 60 ways

  • Now, for the case where one person is to get 1 award and the other 2 people to get two awards each, the number of ways is calculated as;

      ((⁵C₂ × ³C₂)/2) × 3! = 90 ways

  • Thus; total number of ways the awards can be distributed = 60 + 90 = 150 ways.
