Question 738111
The accompanying ven diagram shows the number of students who take various courses. All students in circle a take math. All students in circle b take science. Everyone in circle c take tech.what percentage of the students take math OR tech? I can't make the venn diagram but all I need to know is what does math OR tech mean?
---------
The # who take Math OR tech 
= (# take Math) + (# take tech) - (# take Math AND tech)
