19 Q SIMPLE AND INDEPENDENT PROBABILITY

Front

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 an independent event in probability?

Back

An independent event is an event whose outcome does not affect the outcome of another event.

Front

What is the formula for calculating the probability of a single 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 rolling a die and getting a number greater than 4?

Back

The probability is 1/3, since the favorable outcomes are 5 and 6.

Front

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

Back

The probability is 1/2, as there are two possible outcomes: heads or tails.

Front

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

Back

Multiply the probabilities of each event: 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

The probability is 1/2, as there are 26 red cards out of 52 total cards.

Front

What is the probability of getting tails when flipping a coin twice?

Back

The probability is 1/4, as the possible outcomes are HH, HT, TH, TT.

Front

What is the probability of rolling a number cube and getting a 3?

Back

The probability is 1/6, as there is one favorable outcome (rolling a 3) out of 6 possible outcomes.

Front

What is the probability of choosing a grape from a bowl of 3 grapes and 6 apples?

Back

The probability is 1/3, as there are 3 grapes out of 9 total fruits.
