**MathGuru**, Wednesday, June 29, 2011 at 8:51pmUse z-scores and a z-table to determine your probability.

Formula:

z = (x - mean)/sd

Find both z-values:

z = (60 - 65.5)/2.5

z = (64 - 65.5)/2.5

Once you calculate both z-values, check a z-table for the probability between those two values.

I hope this will help.
