Hi I understand that for a event to have independence it follows that P(A and B)= P(A) x P(B) however i cannot understand this question I have attached the question any help is appreichated.

Hi Maybe you can use another definition: i) Since the result of A will affect that of B, e.g. If A is 1 or 3, P(B)=2/5, If A is 5, P(B)=3/5, hence they are dependent.
