Villain has a 5 46% of the time. I actually did this the "hard" way and enumerated all the possible hands he could have (the probability works also, but math is always open to misunderstanding, so let's take the direct approach)

These are the possible hands he could have, based on available cards
The ones with no 5 (there are 35 of these)
A2 - 2
A3 - 6
A4 - 8
23 - 3
24 - 4
34 - 12

The ones with a 5 (there are 30 of these):
A5 - 6
25 - 3
35 - 9
45 - 12
