At a homeowners' association meeting, a board member can vote yes, vote no, or abstain on a motion. There are three motions on which a board member must vote.
--------------------
Comment: I am assuming "must vote" includes the member may abstain.
--------------------
a) determine the number of points in the sample space
Ans: 3*3 = 9
--------------------
b) construct a tree diagram and determine the sample space.
motion #1: 1y;1n;1? //motion #2: 2y:2n;2? //motion #3: 3y;3n;3?
Determine the probability that the board member votes
c) no, yes, no in that order::1/9
---------------------------
d) yes on exactly two of the motions::2/9
-----------------------------------------------
e) yes on at least one motion: 1 -P(all abstain or all "no") = 1-2/9 = 7/9
