Do you have a venn diagram?
You're supposed to fill in all the regions with their respective probabilities....
Let's start with (i).
That would be P(A or B).
Did you find that one?
can someone help with this question please
A = Paul is late for school
B = Alan is late for school
P(not A or B)=0.68
a) Display the information on a venn diagram
b) on a randomlly selceted day, calculate the probabilty that
i) At least one of Paul or Alan is late for school
ii) Alan is late for school
im not sure how to work on P(B) which is question ii
Btw, I am assuming that with P(not A or B)=0.68 you actually mean P(not(A or B)), just like you showed in your venn diagram.
Note that this is not what Plato assumed.
Now for P(A) only, without P(AB), I believe you calculated it as P(A) - P(AB)=0.24-016.
Only when I calculate that, I get 0.08 instead of 0.8....
