What i do is i look at the table and then find the number that corresponds to the z score which is .3446 which is the area to the left. What happens is the number in the table gives the area to the left of the z-value. If you want the area to the right you need to do 1-the value you get such in this case would be 1-.3446 which is .6554 that number given is also the probability (area=probability). So if you find the area you also know the probability
