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.

Question 1 options:

Two events are disjoint because there are no people belong to both of these events

Two events are disjoint because there are 46 people belong to both of these 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
