Is the area under normal distribution curves with different σ² always the same? ... or never? ...

Luckily, I can't imagine this ever coming up on the GMAT. I've never seen a question where this would be useful, and you need to know little or nothing about distributions for this test.

If you've got a specific problem in mind for this, please share it!

According to google, the area under a normal curve is always equal to one.
