**MathGuru**, Monday, April 18, 2011 at 7:24pmUse z-scores.

Find two z-scores using this formula:

z = (x - mean)/sd

Mean = 38

Sd = 5

Use 36 for x to determine first z-score.

Use 40 for x to determine second z-score.

Once you have both z-scores, check a z-table for the probability between the two scores.

I hope this will help get you started.
