You can put this solution on YOUR website!
Look up 1.1 in the left-most column and go over to the column with 0.03, and read
either 0.8708 or 0.3708, depending on which of the two kinds of tables that are
used today that you are using.

If yours reads 0.3708 then you must add 0.5 to get 0.8708.

If you have a TI-83 or 84 calculator, press 2ND VARS 

Newer calculators have this first:

lower:-9999999
upper:1.13
μ:0
s:1
Paste

Scroll to "Paste" and press ENTER 

Whether your has that or not, make sure it reads this

normalcdf(-99999999,1.13,0,1)

then press ENTER and read 0.8707618393 and round to four decimal places:

0.8708
