Experimental Probability

Front

What is Experimental Probability?

Back

Experimental Probability is the probability of an event based on the results of an experiment or trial. It is calculated by dividing the number of times an event occurs by the total number of trials.

Front

How do you calculate Experimental Probability?

Back

Experimental Probability = \( \frac{\text{Number of times the event occurs}}{\text{Total number of trials}} \)

Front

If a spinner is spun 30 times and lands on blue 12 times, what is the experimental probability of landing on a color that is not blue?

Back

\( \frac{18}{30} = \frac{3}{5} \)

What is the experimental probability of landing on '3' if it occurs 30 times out of 75 spins?

Back

\( \frac{30}{75} = \frac{2}{5} = 40\% \)

What does a bar graph represent in the context of experimental probability?

Back

A bar graph visually represents the frequency of outcomes from an experiment, allowing for easy comparison of different outcomes.

Front

What is the difference between theoretical probability and experimental probability?

Back

Theoretical probability is based on expected outcomes in a perfect scenario, while experimental probability is based on actual results from trials.

Front

If a coin is flipped 24 times and lands on heads 13 times, what is the relative frequency of heads?

Back

\( \frac{13}{24} \)

What is the formula for calculating the percentage of experimental probability?

Back

Percentage of Experimental Probability = \( \left( \frac{\text{Number of times the event occurs}}{\text{Total number of trials}} \right) \times 100 \)

Front

What is the experimental probability of an event that has not occurred at all in 50 trials?

Back

0, since the event has not occurred.

Front

If a spinner has 5 equal sections and lands on one section 15 times out of 50 spins, what is the experimental probability of landing on that section?

Back

\( \frac{15}{50} = \frac{3}{10} \)
