Lesson Topic
Conditional probability
Lesson Outline
We worked on Jared's homework problems in class today. We reviewed the idea behind probability trees while working through one of the problems, and then dissected two word problems so as to understand how the information given verbally can be transformed into numbers using the well-known formula for conditional probabilities, i.e. P ( B | A ) = P ( A and B ) / P ( A ). The left-hand side of the equation translates to 'the probability of event B happening given event A'. The math is always rather straightforward, it's interpreting the problem that is trickier.

Lesson Comments
Despite trying to put on a brave face, I could tell Jared was quite shaken by this weekend's events, so I decided to take it very easy today. We did some math, that I always feel is therapeutic, and then I told him about the history of the discovery of the pulsar (Jocelyn Bell's story was somewhat similar to Rosalind Franklin's - the latter was instrumental in discovering the helix structure of DNA, but all the praise went to her male lab mates - Jared has mentioned her several times in the past few classes, so I thought it might interest him to know of another example in scientific history, that of Jocelyn Bell's).
