Question

In a survey, 125 people were asked to chose one card out of five cards labeled 1 to 5. The results are shown in the table. Compare the theoretical probability and experimental probability of choosing a card with the number 1.

Answer 1

The theoretical probability of choosing a card with the number 1 is (20​%). The experimental probability of choosing a card with the number 1 is (16​%). The theoretical probability is (greater than ) the experimental probability.

Answer 2

The experimental probability to choose card 1 (15/125) is 10 less than the theoretical probability which is 25/125.
