Answer: P = 11/40 + 1/4 + 1/20

Davion Norris · Answer 2

First subtract the number of students who take both subjects from the number of students who take Consumer Education

22-4=18

Then,

subtract the number of students who take both subjects from the number of students who take French

20-4=16

Now,

Add 18,16 and 4 and subtract the sum from the total number of students in the class

=80 - (18+16+4)

=80-38

=42
