Probability (Experimental and Theoretical)

Front

What is experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials or experiments conducted.

Front

What is theoretical probability?

Back

Theoretical probability is the likelihood of an event occurring based on all possible outcomes, calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

How do you calculate experimental probability?

Back

Experimental probability = (Number of times the event occurs) / (Total number of trials).

What is the experimental probability of landing on a multiple of 4 if it landed on a multiple of 4 45 times out of 60 spins?

Back

Experimental probability = 45/60 = 3/4.

How many sides does a normal number cube have?

Back

A normal number cube has 6 sides.

Front

If a spinner landed on blue 12 times out of 30 spins, what is the experimental probability of landing on a color that is not blue?

Back

Experimental probability of not blue = (Total spins - Spins on blue) / Total spins = (30 - 12) / 30 = 18/30 = 3/5.

What is the theoretical probability of rolling a 3 on a number cube?

Back

Theoretical probability of rolling a 3 = 1/6 or approximately 16.67%.

Front

If the experimental probability of rolling a 3 is 15% after 20 rolls, what can you say about the theoretical probability?

Back

The theoretical probability of rolling a 3 is 16.67%, which is slightly higher than the experimental probability of 15%.

Front

What is the formula for calculating the probability of an event?

Back

Probability of an event = (Number of favorable outcomes) / (Total number of possible outcomes).

If Shannon recorded her results after selecting jelly beans 44 times, how do you find the experimental probability of selecting a red jelly bean?

Back

Experimental probability of red jelly bean = (Number of red jelly beans selected) / 44.
