PRACTICE Find Probabilities of Compound and Simple Events

Front

What is the probability of a simple event?

Back

The probability of a simple event is the ratio of the number of favorable outcomes to the total number of possible outcomes.

Front

Define 'compound event' in probability.

Back

A compound event is an event that consists of two or more simple events. The probability of a compound event can be calculated using the probabilities of the individual events.

Front

What is the sample space in probability?

Back

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

Front

If a fair coin is flipped, what are the possible outcomes?

Back

The possible outcomes are Heads and Tails.

Front

What does it mean if an event is 'least likely'?

Back

An event is 'least likely' if it has the lowest probability of occurring compared to other events.

Front

How do you calculate the probability of a compound event?

Back

The probability of a compound event can be calculated by multiplying the probabilities of the individual events if they are independent.

Front

What is the formula for calculating probability?

Back

The formula for calculating probability is: P(Event) = Number of favorable outcomes / Total number of possible outcomes.

Front

What is the probability of drawing a blue marble from a jar containing 3 red, 2 green, and 5 blue marbles?

Back

P(Blue) = Number of blue marbles / Total number of marbles = 5 / (3 + 2 + 5) = 5 / 10 = 1/2.

Front

What is the probability of winning a prize if there are 10 prizes and 2 are won?

Back

P(Winning) = Number of prizes won / Total number of prizes = 2 / 10 = 1/5.

Front

What is the probability of rolling a 3 on a fair six-sided die?

Back

P(3) = Number of favorable outcomes (rolling a 3) / Total outcomes (1-6) = 1 / 6.
