Suppose that the handedness of the last fifteen u. s. presidents is as follows: 40% were left-handed (l)47% were democrats (d)if a president is left-handed, there is a 13% chance that the president is a democrat. based on this information on the last fifteen u. s. presidents, is "being left-handed" independent of "being a democrat"? (a) yes, since 0.40 * 0.47 is not equal to 0.13.(b) no, since 0.40 is not equal to 0.13.(c) no, since 0.47 is not equal to 0.13.(d) yes, since 0.47 is not equal to 0.13.
