You can put this solution on YOUR website!
This is the probability between z=-0.28 and 0.64
normal cdf function on calculator will do this entering the two probabilities and 0 for mean and 1 for sd
probability=0.3492= 34.9%
Between -1 and +1 for z is about 68% probability, so this answer makes sense.
