Question

Which events are independent? Select each correct answer.

A)A spinner is spun and a coin is flipped.
B)One ball is drawn from a bag of balls after another ball is drawn without replacement.
C)Two number cubes are rolled at the same time.
D)White marbles are drawn from a bag of marbles without replacing the marbles

Answer 1

A) A spinner is spun and a coin is flipped

C) Two number cubes are rolled at the same time

Answer 2

Independent events are those events when the happening of one event does not affect the happening the other event.

In the given example we have the following events as independent:

A) A spinner is spun and a coin is flipped

C) Two number cubes are rolled at the same time.

Both these events are independent because the happening of one event does not affect the other in both the cases.

But the options B and D are not independent because in both the cases happening of first event affects the happening of the next event. Therefore, the correct options are A and C.
