help with this math question?

The weight of a sack of potatoes is normally distributed with a mean of 200 ounces and a standard deviation of 20 ounces.

What is the probability (in percent) that a sack has more than 260 ounces of potatoes

How would I do this.
Thanks

with continuity correction, > 260 becomes > 260.5
P[z > (260.5-200)/20)] = 0.0012 <-----
