Question

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?

The ratio 92/200 represents the experimental probability of the coin landing heads up in this experiment.


The ratio 92/200 represents the number of trials in this experiment.

The ratio 92/100 represents the theoretical probability of the coin landing heads up in this experiment.

The ratio 92/100 represents the number of occurrences of the coin landing heads up in this experiment.

Answer 1

The ratio 92/200 represents the experimental probability of the coin landing heads up in this experiment.

Explanation:

Answer 2

The classic definition of probability is: the probability is the ratio of the number of favorable events (m) divided by the number of possible events (n):

`Pr=(m)/(n)`.

Tia performed an experiment where she flipped a coin 200 times. The coin landed heads up 92 times and tails up 108 times (check that 92+108 is exactly 200). Then the theoretical probability of the coin landing heads up in this experiment is

`Pr=(92)/(200)`.

Answer: correct choice is A (the theoretical probability is 1/2).
