The number of right handed students in a mathematics class

There is no photo or anything that could help me solve this.

Step-by-step explanation:

If I am wrong and there is no evidence for this, the number of right handed students in a mathematic class can be absolutely random. You never know who uses the right hand or left hand unless you pay attention, it could even be 50/50. The chances are not determined.

Hahaha, hope this helped!
