P(A)+P(B)-P(A+B)=P(A or B)
P(E)=0.5
0.5+P(M)-P(E+M)=P(E or M)
P(E+M)=0.6
P(E or M)=0.8
so
0.5+P(M)-0.6=0.8
P(M)=0.9

The problem is posed FATALLY INCORRECTLY.
The probability of the intersection of two events ( passing Economics AND Management, 3/5 ) CAN NOT BE GREATER
the probability of any of the two basic events ( passing Economics, 1/2 ).
Posed this way as written in the post, the "problem" is a FAKE and is good for re-cycling, ONLY.
