Front

If I roll a die 100 times, how many times could I expect to roll a number greater than 4?

Back

You could expect to roll a number greater than 4 about 30 times.

Front

What is the probability of rolling a 2 and then an odd number with a pair of dice?

Back

The probability is P(2, then odd) = ⅙ x ½ = 1/12.

Front

How many total outcomes are there when rolling a die and flipping a coin?

Back

There are 12 total outcomes.

Front

Define independent events in probability.

Back

Independent events are events where the outcome of one event does not affect the outcome of another.

Front

What is the formula for calculating the probability of independent events?

Back

P(A and B) = P(A) x P(B) for independent events A and B.

Front

What is the probability of flipping a coin and getting heads?

Back

The probability of getting heads when flipping a coin is 1/2.

Front

If the probability of an event happening is 0.3, what is the probability of it not happening?

Back

The probability of the event not happening is 1 - 0.3 = 0.7.

Front

What is a tree diagram in probability?

Back

A tree diagram is a visual representation of all possible outcomes of an event.
