Question 11 • Common Core Algebra II - MA3111 B-IC

Which best describes independent events?

Answer
A
The results of all events have different individual probabilities.
B
The results of any previous events affects the probability of future events.
C
The results of all events have the same individual probability.
D
The results of all previous events do not affect the probability of future events.

Explanation

Independent events are events where knowing the results of earlier events does not change the probability of a later event. Therefore, “the results of all previous events do not affect the probability of future events” is the best description. The events do not need to have the same individual probabilities.
