who has the best hand?

[coldcards2]

I would like to know if somebody can help me figure out how to calculate the probability of me having the best hand at the river. If I'm tyring to figure out if I am even money or not, I need to know the probability of me having the best hand. I cant seem to figure it out. If someone would take the time to give me any explanation, it would be greatly appreciated. Thanx
