Question 5 3 pts If PA 736 PB 16 and PA and B 0 what can
Question 5 3 pts If P(A) = 7/36, P(B) = 1/6 and P(A and B) = 0, what can you say about P(A or B)?
13/36
19/72
7/72
There is not enough information to determine P(A or B).
Solution
If P(A and B)=0 ,it means two events are mutually exclusive
P(A or B)=P(A)+P(B)-P(A and B)
P(A or B)=P(A)+P(B)-0
P(A or B)=7/36+1/6
=13/36
SO option 1 is the correct one
