Use the normal curve to figure the chance that the sum of the draws is between 224 and 288. First change 224 and 288 to Z scores by subtracting the EV and dividing by the SE. (Remember Z=(value-ave)/SD so for a chance process it's Z=(value-EV)/SE.) What the Z score for 224? What the Z score for 288? Now use the normal curve to find the chance that
