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.
The experimental probability is [tex]\frac{10}{15+10+40+20+40}=8\%,[/tex] while the theoretical probability, assuming random selection, is [tex]\frac{1}{5}=20\%,[/tex] so the theoretical probability is greater than the experimental probability.
