Sarah is rolling a number cube, numbered 1-6, and recording the number that shows up on each roll.

Event A describes the probability of getting a 4 on the first roll.

Event B describes the probability of getting a 4 on the second roll.

Which statement correctly explains whether the events A and B are dependent or independent?

Question 1 options:

A. A and B are dependent events, because the probability of the first roll will affect the probability of the second roll.

B. A and B are independent events, because the probability of the first roll will affect the probability of the second roll.

C. A and B are independent events, because the probability of the first roll will not affect the probability of the second roll.

D. A and B are dependent events, because the probability of the first roll will not affect the probability of the second roll.

    C

    Step-by-step explanation:

    Definition: Two events, A and B, are independent if the fact that A occurs does not affect the probability of B occurring.

    Event A = getting a 4 on the first roll.

    Event B = getting a 4 on the second roll.

    True option C: A and B are independent events, because the probability of the first roll will not affect the probability of the second roll.
