Probability Help

<p>Okay, I've been thinking of this one for a while. The deal is I don't know how to solve problems that have anything to do with probability, even the simplest concept. This has been bothering me for a long time now; I'm a sophomore presently, and when i took my PLAN act in freshman year, i got every question that had to with it wrong. On the PSAT, once i looked at the question asking to find the probability, i didn't even bother trying to understand what the question was asking or if i could answer it. The reason is that i didn't pay attention at all in high school, meaning i don't comprehend even the basics. Realizing that i couldn't avoid it for long as i plan to get a high score on my ACT and ACT while getting National Merit Finalist Award for psat, I went to Khan Academy and i watched their 9 videos series on probability, but the annoying thing was that i came out even more confused. It's been bothering me so much that i plan to take AP statistics Junior year just to get prepared for all the Standardized tests. so the question is
Is there any website out there that explains Probability thoroughly and easily? Thanks</p>
