In a group of 24 people, 10 study Physics, 15 study Chemistry and
18 study at least one subject.
Find the number of people who
do not study any of the subject.
Show steps pls

n = 24

p(a) = 10/24

p(b) = 15/24

[ p(a) + p(b) - [p(a) ×p(b)] ] -1 = answer

[ 35/24 - 6/24 ] -1 = 39/24 - 24/24 = 5/24

Explanation:

There are 24 people total and 18 of them study at least one subject. So that must mean 24 - 18 = 6 people do not study any of the subjects mentioned.

The values of 10 and 15 aren't used at all.

y + 11 = (1/4)(x + 16)
