Module 10 Review

Front

What is experimental probability?

Back

Experimental probability is the likelihood of an event occurring based on the results of an experiment or simulation, calculated as the number of times the event occurs divided by the total number of trials.

Front

What is theoretical probability?

Back

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

Front

What does it mean if an event is described as 'impossible'?

Back

An event is described as 'impossible' if it cannot occur at all, meaning the probability of the event is 0.

Front

What does it mean if an event is described as 'certain'?

Back

An event is described as 'certain' if it is guaranteed to occur, meaning the probability of the event is 1.

Front

What is the probability of landing on an odd number with a fair spinner divided into 6 equal sections (1, 2, 3, 4, 5, 6)?

Back

The probability is 3/6 or 1/2, as there are three odd numbers (1, 3, 5) out of six total sections.

Front

How do you calculate relative frequency?

Back

Relative frequency is calculated by dividing the number of times an event occurs by the total number of trials or observations.

Front

What is the probability of selecting a red marble from a jar containing 4 yellow, 11 green, and 9 blue marbles?

Back

The probability is 0, or 'impossible', since there are no red marbles in the jar.

Front

If a coin is tossed four times, what is the theoretical probability of getting heads at least two times?

Back

The theoretical probability is 11/16.

Front

What does 'equally likely' mean in probability?

Back

'Equally likely' means that all outcomes have the same chance of occurring.

Front

What is the total number of outcomes when tossing a coin twice?

Back

The total number of outcomes is 4: (HH, HT, TH, TT).
