Suppose that the handedness of the last 15 u. s. presidents is as follows:

(i) 40% were left-handed (l)
(ii) 47% were democrats (d)
(iii) if a president is left-handed, there is a 13% chance that the president is a democrat.

what is the probability that a randomly chosen u. s. president is left-handed and a democrat?

a: 0.40 * 0.47 = 0.1880
b: 0.40 * 0.13 = 0.0520
c: 0.47 * 0.13 = 0.0611
d: 0.40/0.47 = 0.8510
e: 0.40/0.13 = 3.0769
f: 0.47/0.13 = 3.6154
