What is probability?

Back

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

Front

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

Back

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

Front

What does 'AND' mean in probability?

Back

'AND' indicates that both events must occur. The probability is calculated by multiplying the probabilities of each event.

Front

What does 'OR' mean in probability?

Back

'OR' indicates that at least one of the events must occur. The probability is calculated by adding the probabilities of each event.

Front

How do you calculate the probability of independent events?

Back

For independent events, multiply the probabilities of each event occurring.

Front

What is a sample space?

Back

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

Front

What is a favorable outcome?

Back

A favorable outcome is an outcome that satisfies the conditions of the event we are interested in.

Front

How do you find the probability of drawing a specific item from a group?

Back

Divide the number of that specific item by the total number of items in the group.

If there are 5 brown cows and 10 white cows, what is the probability of selecting a brown cow?

Back

The probability is 5/(5+10) = 5/15 = 1/3.
