Question 868376: Use the given information to find the indicated probabilities. P
A) P(A)=.7, P(B)=.9, P(A U B)=1.2
Find P (A Or B)
B) A and B are mutually exclusive. P (A U B)=1.5, P(B) =.7
i) Find P(A)
ii) Find P(A')

A)P(A or B or both, for that matter)=1.2=P(A U B)
B)
i) 1.5-.7=.8=P(A)
.
ii) P(A')=P(B)=.7 since none of the rest of the sample space is given.
