# what’s the chance of having a flush?

As you’ve probably guessed, my blog post today is all about probability! This is the topic that my Precalculus students have been studying lately. I decided to show you a few different problems that either involve combinations or where people THINK they have to use combinations when they actually don’t! This is advice that I taught myself to follow as I did more and more with probability, and I hope that it will help you to choose the easiest way to solve these types of problems too.

# volumes the calculus way

Hello everyone! I hope you all had a lovely Spring Break. It still feels like winter here, but since it’s April we can just pretend like it’s Spring! As my seniors are gearing up for AP tests at the beginning of May I will be including videos of some of the final chapters that they’ve been studying this past month. The topic today is how to find the volume of a solid by using cross-sections. Both AB and BC Calculus students study this topic so I will include one video for both classes. I’ve shown the most frequent shapes that Calculus books use for the cross-sections (square, equilateral triangle, circle etc.) Hopefully this will help some of you as you begin reviewing everything this month for the AP exams!!
