Ineed out of fifty students, twenty five are taking math competition classes and 29 are taking geometry. given that 12 are taking history and no math classes and nineteen students are in both math classes. a. how many students are in neither class? if you , i'll mark you the brainliest !

15

Step-by-step explanation:

For these kind of problems, its best to use a Venn Diagram.

Lets break down the information:

There are 50 students total.

25 take Math competiton classes.

29 take Geometry

12 take history and no math classes

19 take both math classes

Now, make a Venn Diagram.

[Look at the photo attached. Also, the blank spaces in the Venn Diagram are ones that no student takes.]

The 12 taking history and no math classes and 3 kids not taking any of those classes look like they're the only ones not taking either math class.

12 + 3 = 15.

So the answer is 15.

[I'm not sure if this is correct or if I made a mistake so please let me know! Thank you! I hope this helps!]
