Experimental Probability — Quiz

Question 9 • Grade 7 Mathematics

Melanie and three of her classmates worked as a team to find the experimental probability of a spinner landing on a blue section. Melanie performed 10 trials. Enrique performed 50 trials. Veronique performed 300 trials. Juanita performed 500 trials. Compare the four experiments. Which student is most likely to get an experimental probability best suited for predicting frequencies?

Answer
A
Veronique
B
Juanita
C
Melanie
D
Enrique

Explanation

An experimental probability is generally more reliable for predicting future frequencies when it is based on more trials. Juanita performed 500 trials, more than Veronique’s 300, Enrique’s 50, or Melanie’s 10. Therefore, Juanita is most likely to get the best estimate.
