Question

tia performed an experiment in which she flipped a coin 100 times. the coin landed heads up 49 times and tails up 51 times. the number 100 represents the blank in the experiment. 49/100 represents the blank of the coin landing heads up.

Explanation:

• In a coin - flipping experiment, the total number of times the coin is flipped (100 times here) is the number of trials. So 100 represents the number of trials in the experiment.
• The fraction $\frac{49}{100}$ is calculated as $\frac{\text{number of heads}}{\text{total number of trials}}$, which is the relative frequency (or experimental probability) of the coin landing heads up.

Answer:

First blank: number of trials
Second blank: relative frequency
