Experimental Probability — Quiz

Question 1 • Grade 7 Mathematics

Tia performed an experiment where she flipped a coin 200 times. The coin landed heads up 92 times and tails up 108 times. Which statement about this experiment is true?

Answer
A
The ratio 92 over 200 represents the number of occurrences of the coin landing heads up in this experiment.
B
The ratio 92 over 200 represents the number of trials in this experiment.
C
The ratio 92 over 200 represents the experimental probability of the coin landing heads up in this experiment.
D
The ratio 92 over 200 represents the theoretical probability of the coin landing heads up in this experiment.

Explanation

Experimental probability is the number of times an outcome occurred divided by the total number of trials. Heads occurred 92 times in 200 flips, so 92/200 is the experimental probability of landing heads. It is not the theoretical probability, which for a fair coin is 1/2.
