Question 1182724
.
probability a student will pass an economics exam is 1/2
probability the student pass economics and management exam is 3/5
probability that the student pass economics or management exam is 4/5
find the probability the students pass a management exam
~~~~~~~~~~~~~~~~~



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.
