5. Jean-Luc and William are sometimes late for their company-wide meeting. Let J be the event that Jean-Luc is late, and W be the event that William is late. For any given day, we have the probabilities P(J) = 0.2, P(J NW) = 0.1, and P(J NW) = 0.5. (Hint: If you get stuck, you might find it helpful to refer back to some basic rules of Boolean algebra from Week 1.) (a) Given that William is late, what is the probability that Jean-Luc is also late? (b) Are Jean-Luc's and William's lateness linked? Justify your answer using probability concepts that we covered
