⟩ In a group of 15, 7 have studied Latin, 8 have studied Greek, and 3 have not studied either. How many of these studied both Latin and Greek?A. 0B. 3C. 4D. 5

L=7

G=8

Total number of students(U)=15

Number of students who study neither of them (N)=3

draw a simple diagram representing the above situation.

we need to find out L INTERSECTION G.

Thus we have,

L UNION G + N = 15

L UNION G = L + G - L INTERSECTION G = 7 + 8 - L INTERSECTION G

L INTERSECTION G= 7 + 8 +N-15

= 7+8+3-15

= 3
