Consider the following two events:
A = the event a person is a Strong Republican,
B = the event a person is ok to a woman getting an abortion for any reason.
Based on these data, select the correct answer about these two events.

|
Two events are not disjoint because there are no people belong to both of these events |
|
Two events are not disjoint because there are 46 people belong to both of these events |

Consider the following two events:
A = the event a person is a Strong Democrat,
B = the event a person is ok to a woman getting an abortion for any reason.
Based on these data, decide whether these two events are independent according to probability.
Question 6 options:
Two events are independent because P(A)xP(B) = P(A and B) is true |
|
Two events are not independent because P(A)xP(B) = P(A and B) is true |
|
Two events are independent because P(A)xP(B) = P(A and B) is not true |
|
Two events are not independent because P(A)xP(B) = P(A and B) is not true |
