From 4.2 to 5.1 Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! p(4.2 < x < 5.1) = p( -1 < z < 0) = normalcdf(-1,0) = .3413 0r 34.13%
area Under Normal curve between z = -1 and z = 0
........
Area under the standard normal curve depends on the constraints placed on z-values
Note: z = 0 (x value: the mean) 50% of the area under the curve is to the left and 50% to the right
