Answer:

3

Step-by-step explanation:

  • <em>Each of the seven happy clowns has a red nose.</em>

This means there are (15-7) 8 sad clowns.

  • <em>Five of the sad clowns have red noses. </em>

This means out of 8 sad clowns, 5 have red noses. So the clowns that have to act sad and have red noses are (8-5) 3.
