Hello, dear reader! Tutor Paul and I wrote a hand-out on conditional probability that we hope will help students understand this idea. I first encountered it while tutoring a student who was taking Genetics 301 at Texas A&M University. Discussing it amongst ourselves, we found conditional probability to be confusing, but eventually we found ways of explaining it that cleared up the confusion. Those ideas became the foundation of the hand-out below.
Happy studying! Feel free to leave a comment below if you have any suggestions for us. Thanks for stopping by.
