A spinner has 5 sections of equal size labeled P, Q, R, and T.
The arrow of this spinner was spun 15 times and landed 4 times on the section labeled Q.

• The experimental probability is ¹/₅, and the theoretical probability is ¹/₅.

• The experimental probability is ¹/₅, and the theoretical probability is ⁴/₁₅.

• The experimental probability is 4/₁₅, and the theoretical probability is ¹/₅.

• The experimental probability is 4/₁₅, and the theoretical probability is ⁴/₁₅.
