Front

What is the probability of selecting a blue marble from a bag containing 6 red, 5 blue, and 4 green marbles?

Back

The probability of selecting a blue marble is 5/(6+5+4) = 5/15 = 1/3.

Front

What is the probability of selecting a blue marble from each of two bags, where the first bag has 6 red, 5 blue, and 4 green marbles, and the second bag has 3 red, 2 blue, and 4 green marbles?

Back

The probability of selecting a blue marble from the first bag is 5/15 and from the second bag is 2/9. Therefore, the combined probability is (5/15) * (2/9) = 2/27.

Front

How do you calculate the probability of selecting a specific card from a set of cards?

Back

The probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Front

What is the probability of selecting a C or an even number from a bag containing 9 cards: 3, J, C, 6, E, 8, 9, 5, and A?

Back

There are 3 favorable outcomes (C, 6, 8) out of 9 total cards, so the probability is 3/9.

Front

What is the probability of tossing a coin and getting tails?

Back

The probability of getting tails is 1/2.

Front

What is the probability of rolling a number greater than 3 on a number cube with numbers 1 through 6?

Back

The numbers greater than 3 are 4, 5, and 6, which gives a probability of 3/6 = 1/2.

Front

What is the combined probability of two independent events occurring?

Back

The combined probability is the product of the probabilities of each event.

Front

If a coin shows tails and a number cube shows a number greater than 3, what is the combined probability?

Back

The probability of tails is 1/2 and the probability of rolling greater than 3 is 1/2. Therefore, the combined probability is (1/2) * (1/2) = 1/4.

Front

What is the total number of outcomes when rolling a number cube?

Back

There are 6 possible outcomes when rolling a number cube (1, 2, 3, 4, 5, 6).

Front

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.
