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:
$\displaystyle P(B|A)=\frac{P(B \cap A)}{P(A)}$
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.
