If your holding JJ what is the probability of an A or K or Q appearing in the flop?

I came up with approximately 57% of the time an overcard will come on the flop when you are holding JJ. 57% for some reason just seems a little high. Could somebody verify if that approximation is correct.

Here are my calculations, I solved the problem two different ways.

Method 1
=========
12/50 + (38/50 * 12/49) + (38/50 * 37/49 * 12/48)

Method 2
=========
1 - (38/50 * 37/49 * 36/48)

Thanks
