The probability is about 85.29%.

To do this, you need to first find the z-score on each end of the interval. Then, you can subtract the percents to find the percent in the middle.

Lower:
(1000 - 1252) / 129 = -1.18 which gives a probability of 11.9%

Upper:
(1500 - 1252) / 129 = 1.92 which gives a probability of 97.19%

97.19 - 11.9 = 85.29

The probability is 0.8536.

Z-scores are calculated using the formula 

z = (X - μ)/σ

For the lower limit we have
z = (1100-1252)/129 = -1.18

For the upper limit we have
z = (1500-1252)/129 = 1.92

Using a z-table (http://www.z-table.com) we see that the area to the left of the lower limit, less than that, is 0.1190.  The area to the left of the upper limit, less than that, is 0.9726.  The area between them is found by subtracting:

0.9726 - 0.1190 = 0.8536
