Q5. Extend Theorem 5 (P(AUB) = P(A) + P(B) = P(ANB)), proved in class, to three
events, A, B and C, by finding an expression for P(AUBUC) in terms of the
probabilities of A, B and C, of their pair-wise intersections, and the intersection of
all three events. (Hint: Begin by considering AUB as a single event).
Can you help me understand this analysis?
A 95.7% confidence interval is shown for the intention-to-treat analysis (accounting for alpha spending in interim analyses), and 95% confidence intervals are shown for the other two analyses. The widths of the confidence intervals have not been adjusted for multiplicity. The dashed line indicates the noninferiority margin of 4 percentage points.

Select one of the following statements. a. No, because more money should have been earned through simple interest than compound interest. b. Yes, because more money was earned through simple interest. For simple interest you earn interest on interest, not just on the amount of principal. c.
