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

The probability of an event is calculated as: P(Event) = Number of favorable outcomes / Total number of possible outcomes.

Front

What is the probability of drawing a blue marble from a bag containing 4 red, 2 blue, and 3 green marbles?

Back

P(Blue) = 2 / (4 + 2 + 3) = 2 / 9.

Front

What is the probability of flipping heads on a fair coin?

Back

P(Heads) = 1/2.

Front

What is the combined probability of two independent events occurring?

Back

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

Front

If a die is rolled, what is the probability of rolling a number greater than 4?

Back

P(Number > 4) = 2/6 = 1/3.

Front

How many outcomes are there when rolling two dice?

Back

There are 6 * 6 = 36 possible outcomes when rolling two dice.

Front

What is the probability of rolling a sum of 8 with two dice?

Back

P(Sum = 8) = 5/36.

Front

What is experimental probability?

Back

Experimental probability is the probability based on the actual results of an experiment.

Front

Why is flipping a coin 100 times more accurate for experimental probability than flipping it 10 times?

Back

Flipping a coin 100 times provides more data, leading to a more accurate estimate of the true probability.
