Question

In a​ survey, 125 people were asked to choose 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 2.

Answer 1

The experimental probability is
`(10)/(15+10+40+20+40)=8\%,` while the theoretical probability, assuming random selection, is
`(1)/(5)=20\%,` so the theoretical probability is greater than the experimental probability.
