A spinner has 5 sections of equal size labeled P, Q, R, S, and T. The arrow of this spinner is spun 15 times and landed 4 times on the section labeled Q.
Which statement best describes the experimental probability and theoretical probability of the arrow landing on the section labeled Q? 

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

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

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

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

A spinner is divided into 4 equally sized selections. The sections are blue, green, red, and yellow. The results of 1000 spins are shown in the table.
