Another probability?

The gypsy moth is a serious threat to oak and aspen trees. A state agriculture department places ts throughout the state to detect the moths. When traps are checked periodically, the mean number of moths trapped is only 0.5, but some traps have several moths. The distribution of moth counts is discrete and strongly skewed, with standard deviation 0.7. Use the central limit theorem (normal approximation) to find the probability that the average number of moths in 80 traps is greater than 0.55. Give your answer in a decimal form with 3 decimal places.
