Front

What is the probability of selecting a green or red marble from a bag containing 9 green, 5 yellow, and 6 red marbles?

Back

The probability is \( \frac{3}{4} \).

Front

If Mrs. Cox picks one marble from a bag of 5 blue, 4 red, and 3 orange marbles, replaces it, and picks another, what is the probability that she picks two that are not orange?

Back

Front

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

Back

The probability is \( \frac{39}{52} \).

Front

What is experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials.

Front

What is the formula for calculating the probability of two independent events occurring?

Back

The formula is \( P(A) \times P(B) \).

Front

If you roll a number cube 50 times and get a 1 on 10 rolls, what is the experimental probability of rolling a 1?

Back

The experimental probability is \( \frac{10}{50} = \frac{1}{5} \).

Front

What is the probability of picking a blue marble, replacing it, and then picking a red marble from a bag containing 4 blue and 3 red marbles?

Back

The probability is \( \frac{4}{7} \times \frac{3}{7} \).

Front

How do you calculate the probability of an event not occurring?

Back

The probability of an event not occurring is \( 1 - P(A) \).

Front

What is the total number of outcomes when rolling a six-sided die?

Back

The total number of outcomes is 6.

Front

If a bag contains 10 marbles (4 red, 3 blue, 3 green), what is the probability of picking a red marble?

Back

The probability is \( \frac{4}{10} = \frac{2}{5} \).
