Does anyone know the answer and how to solve?

Top left = 2
Top right = 4
Bottom left = 1
Bottom right = 5

Let me know if you need an explanation.

First box should be: 2 bc of the second statement
second box (top right): 5 bc 12 students total, subtract from rest (u do this last)
third box: 1 bc all that’s leftover from first box
fourth box (bottom right) 5 bc of third statement
basically, for two way tables each box must apply/be applied to two topics. hope this helps
