Probability of Independent Events

Question 6 • CA-Common Core Geometry DVHS Sem. 2

Spinning a 4-section spinner twice can be described as which type of event?

Answer
A
It is an independent event. The outcome of the second spin is unaffected by the outcome of the first spin.
B
It is a dependent event. The outcome of the second spin is affected by the outcome of the first spin.
C
It is a simple event. Spinning a spinner is a single event.
D
It is an impossible event. A spinner cannot land in two sections.

Explanation

The result of one spin does not change the spinner or affect the probabilities on the next spin. Each spin has the same four possible sections, so the spins are independent events. The correct choice is A: the second spin is unaffected by the first spin’s outcome.
