@neha......u can check the independence of events A and B by using P(A intersection B) = P(A).P(B)
Where P(A intersection B) = p(5<=X<=8)
P(A) = p(X>=5)
P(B) = p(3<=X<=8)
U ll see equality will not hold, these two aren't independent.
Or alternatively this can be seen by the definition of Events A and B. But for 100% surety above method always works!
