Probability & Populations Review

Front

What is probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 (impossible) and 1 (certain).

Front

What is a sample space?

Back

A sample space is the set of all possible outcomes of a probability experiment.

Front

What is an event in probability?

Back

An event is a specific outcome or a set of outcomes from a probability experiment.

Front

How do you calculate the probability of an event?

Back

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

Front

What is the difference between experimental and theoretical probability?

Back

Experimental probability is based on actual experiments and observations, while theoretical probability is based on mathematical calculations.

Front

If you flip a coin, what are the possible outcomes?

Back

The possible outcomes are heads (H) and tails (T).

Front

What is a combination in probability?

Back

A combination is a selection of items from a larger set where the order does not matter.

Front

How many combinations can be made with 3 sandwiches and 2 drinks?

Back

Total combinations = 3 sandwiches x 2 drinks = 6 combinations.

Front

What is the probability of drawing a red card from a standard deck of cards?

Back

The probability is 26/52 or 1/2, since there are 26 red cards in a deck.

Front

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

Back

If an event is certain, it means it will definitely happen, with a probability of 1.
