Unit 7 Probability

Front

What is probability?

Back

Probability is a measure of how likely an event is to occur, expressed as a number between 0 and 1, where 0 means the event will not happen and 1 means it will definitely happen.

Front

What is theoretical probability?

Back

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

Front

What is experimental probability?

Back

Experimental probability is the likelihood of an event happening based on actual experiments or trials, calculated as the number of times the event occurs divided by the total number of trials.

Front

If a spinner has 4 equal sections, what is the theoretical probability of landing on any one section?

Back

The theoretical probability of landing on any one section is 1/4 or 25%.

Front

What is the probability of flipping a coin and landing on heads?

Back

The probability of flipping a coin and landing on heads is 1/2 or 50%.

Front

How do you calculate the expected number of outcomes in probability?

Back

To calculate the expected number of outcomes, multiply the probability of the event by the total number of trials.

Front

What is the formula for calculating probability?

Back

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

Front

What is the probability of not landing on a specific color if the probability of landing on that color is 0.33?

Back

The probability of not landing on that color is 1 - 0.33 = 0.67 or 67%.

Front

If Shannon selects a jelly bean 44 times and picks red 11 times, what is the experimental probability of picking a red jelly bean?

Back

The experimental probability of picking a red jelly bean is 11/44 or 1/4.

Front

What is a bar graph used for in probability?

Back

A bar graph is used to visually represent the frequency of different outcomes in probability experiments.
