A useful graphical method of constructing the sample space for an experiment is:
A. a histogram
B. an ogive
C. a tree diagram
D. a pie chart

If A and B are mutually exclusive events with P(A) = 0.70, then P(B):
A. cannot be larger than 0.30
B. cannot be smaller than 0.30
C. can be any value between 0 and 1
D. can be any value between 0 and 0.70
