I've googled and couldn't find this answer and I won't even begin to attempt to figure it out on my own.

Does anyone know how to calculate or know where to look?

The purpose is that I'm often in games that play very big pre-flop and its fairly easy to find myself limping with the ability to 4 bet. There are two action players that are often opening and 3 betting a massive range. I'd like to understand the likelihood of hitting a straight if I 4 bet a wrap in that scenario and am called when the money is likely near all in PF. I know I have other ways to win and can lose to flushes, bigger straights, boats, etc. Just trying to keep the question simple and then go from there.

Thanks.
