MATH!!!!AAARRRRGGGGGHHHHH!!!!!

Can someone please help me with these probability solutions. I do not want the answer. I want the solution to finding the answer. I want to find the differences in probability of flopping an open ended straight draw, flush draw, open ended straight flush draw, and flopping a flush draw OR an open ended straight draw with suited connectors, connectors, 1 gappers both suited and connected. Drawing to the nuts(staight), etc.....

I would love to chat with someone on how to go through these things. I can get started, but I hit bumps, that I can't figure out.
