Unformatted text preview: C) Suppose you perform an experiment where there are eight possible outcomes. If every subset of outcomes constitutes an event, how many distinct events are there? D) A point X is selected at random (with uniform probability) from a line segment AB with midpoint O . Find the probability p that the line segments AX , XB , and AO can form a triangle. ( Hint: In a triangle, the sum of the lengths of any two sides must be at least the length of the third side.) E) Let ( , A ,P ) be a probability space. (a) Prove (using the denition of probability space) that if E and F are events with E F , then P ( E ) P ( F ). (b) Prove that given any two events E and F , P ( E T F ) P ( E ) + P ( F )-1.
