What we did in 2 hours:

Finishing our last examples on Binomial Distribution, we moved on to Normal Distributions. The questions are getting tedious, do note how we focus on simplifying the context into workable parts and being ready to deal with concepts from other chapters.

What you take home:

Worked solutions for Q2 and Daily Dose are linked here:
