How do you convert a decimal to a percent?

Back

To convert a decimal to a percent, multiply the decimal by 100 and add a percent sign. For example, 0.528 x 100 = 52.8%.

Front

What is the expected outcome when rolling a number cube (die) 40 times regarding odd numbers?

Back

When rolling a number cube 40 times, you would expect to land on an odd number approximately 20 times, since there are 3 odd numbers (1, 3, 5) out of 6 total numbers.

Front

If there are 20 marbles in a jar, how do you calculate the probability of not drawing a green marble?

Back

To find P(not green), first determine the number of non-green marbles. If there are 10 green marbles, then P(not green) = (20 - 10) / 20 = 0.5.

Front

How do you convert a fraction to a percent?

Back

To convert a fraction to a percent, divide the numerator by the denominator and multiply by 100. For example, (2/5) x 100 = 40%.

Front

What is the difference between experimental and theoretical probability?

Back

Experimental probability is based on actual experiments and observations, while theoretical probability is based on expected outcomes in a perfect scenario.

Front

What is the formula for calculating probability?

Back

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

Front

How do you express a probability as a decimal?

Back

To express a probability as a decimal, divide the number of favorable outcomes by the total number of possible outcomes. For example, P(rolling a 3) on a die = 1/6 = 0.1667.

Front

What is the probability of rolling an even number on a number cube?

Back

The probability of rolling an even number (2, 4, 6) on a number cube is P(even) = 3/6 = 0.5.

Front

How do you find the probability of multiple independent events occurring?

Back

To find the probability of multiple independent events occurring, multiply the probabilities of each individual event. For example, P(A and B) = P(A) x P(B).

Front

What is the significance of the percent symbol (%) in probability?

Back

The percent symbol (%) indicates a ratio out of 100, making it easier to understand and compare probabilities.
