when a standard distribution plot is skewed right, where are the mean and median found?

probability and statistics 
Ann,
Is this right? and how can I break it down if needed?
A factoryâ€™s worker productivity is normally distributed. One worker produces an average of 75 units per day with a standard deviation of 20. Another worker produces at an average rate of 65 per day with a standard deviation of 21. What is the probability that during one week (5 working days) worker 1 will out produce worker 2? = (10%)
