You roll two number cubes.
Let event A = You roll an even number on the first cube.
Let event B = You roll a 4 on the second cube.
Are the events independent or dependent? Why?
O A. Dependent, because 4 is an even number.
B. Independent, because the outcome of the first roll doesn't affect
the outcome of the second roll.
C. Independent, because they have no outcomes in common.
O D. Dependent, because both cubes have six sides.

Answer:

B) Independent, because the first cube being an even number cannot affect the second cube being 4.

Even if the first cube was a odd number,

that wouldn't have mathematically changed anything about the second cube's outcome.
