You have a 40% chance of hitting the flop with AK, and thats just the ace/king, you can also pickup straight/flush draws which add a few more percent.
Just raise your 3-5bb with it ( more if limpers ), if it hits bet it, if it misses fold - until you're more experienced.
to pair one of your hole cards on the flop is 40%?
I think its nearer 33%, even money through to the river.
