What is the definition of 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

P(Event) = Number of favorable outcomes / Total number of outcomes.

Front

What does it mean if the probability of an event is 0?

Back

It means that the event is impossible and will not occur.

Front

What does it mean if the probability of an event is 1?

Back

It means that the event is certain and will definitely occur.

Front

How do you calculate the probability of two independent events occurring together?

Back

P(A and B) = P(A) * P(B).

Front

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

Back

P(Red card) = 26/52 = 1/2.

Front

If a coin is flipped, what is the probability of getting heads?

Back

P(Heads) = 1/2.

Front

What is the probability of drawing a yellow M&M from a bowl containing 4 yellow, 6 orange, 3 green, 5 blue, and 2 brown M&Ms?

Back

P(Yellow) = 4/(4+6+3+5+2) = 4/20 = 1/5.

Front

What is the probability of NOT drawing a lime from a box containing 3 limes, 5 grapes, and 2 oranges?

Back

P(NOT lime) = (5+2)/(3+5+2) = 7/10.

Front

What is the probability of drawing 2 yellow markers from a box containing 2 yellow, 4 red, 6 blue, and 3 green markers?

Back

P(2 yellow) = (2/15) * (1/14) = 1/105.
