Zhang Hua has to go through four traffic posts A, B, C, and D on his way to school. The probability of encountering a red light at posts A and B is $\frac{1}{2}$ each, and at posts C and D, it is $\frac{1}{3}$ each. Assuming that the events of encountering red lights at the four traffic posts are independent, let X represent the number of times he encounters red lights.  
(1) If x≥3, he will be late. Find the probability that Zhang Hua is not late.  
(2) Find $E(X)$, the expected number of times he encounters red lights.
