Help with highlighted please
You can draw two separate diagrams: one for Wednesday and one for Thursday, because they are independent. Start with Alison on both days (because David is dependent on Alison).
I would draw two separate diagrams like the one you drew, for each day, otherwise it might get complicated trying to figure out all the values. You don't have to draw the diagrams for this question by the way ... it is just a visualisation aid.
But i dont know how i would draw a tree diagram or seperate venn diagrams.
COuld you show me please?
