Answer:
(C) No, since 0.47 is not equal to 0.13.
Step-by-step explanation:
We have two events, A and B.
I am going to say that P(A) is the probability that a president is left-handed.
I am going to say that P(B) is the probability that a president is a Democrat.
P(B/A) is the probability that the probability that the president is a Democrat, given that he is left-handed.
If P(B/A) = P(A), then the events are independent.
In this problem, we have that P(B/A) = 0.13 and P(A) = 0.47. So, "being left-handed" is not independent of "being a Democrat" and the correct answer is
(C) No, since 0.47 is not equal to 0.13.
