Given:
A = 14
B = 29

Solution by venn diagram see attached image.

A U B = 9 + 5 + 24
A U B = 38

u - (A U B) = 40 - 38
u - (A U B) = 2

so there are 2 students who are neither in the classes.
in either classes are 9 and 24
0
Thanks for the venn diagram. What about either class? The one you gave is neither class?
it each class or both class?
9 and 25
9 and 24 i mean
38 either 2 neither
