A = Paul is late for school
B = Alan is late for school
P(A+B)= 0.68 <<<< This is mean't to have a line over it to make it NOT
Display this information on a Venn diagram. (1)
On a randomly selected day, calculate the probability that
i. At least one of Paul or Alan is late for school. (2)
ii. Alan is late for school. (2)
Calculate the probability that Alan is late for school given that Paul is late.

Re: Probability help!!!
Hint: Draw a Venn diagram with two circles that overlap corresponding to A and B. The common part is A and B and the area outside both circles is NOT(A OR B).
