What is a compound event?

Back

A compound event is an event that consists of two or more simple events. For example, rolling a die and flipping a coin simultaneously.

What is the probability of rolling an odd number on a 6-sided die?

Back

There are 3 odd numbers (1, 3, 5) out of 6 possible outcomes, so the probability is 3/6 or 1/2.

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

Back

There are 2 possible outcomes (heads or tails), so the probability of getting tails is 1/2.

What is experimental probability?

Back

Experimental probability is the probability based on the results of a series of trials or experiments.

Front

What is the probability of rolling an even number and then an odd number on a 6-sided die?

Back

The probability of rolling an even number is 1/2 and rolling an odd number is also 1/2. Therefore, the combined probability is 1/2 * 1/2 = 1/4.

What is the total number of outcomes when spinning a spinner with 4 equal sections?

Back

The total number of outcomes is 4, one for each section of the spinner.

Front

If a spinner is spun twice, what is the probability of getting a specific color both times?

Back

If there are 4 colors, the probability of getting a specific color on one spin is 1/4. Therefore, the probability of getting that color twice is (1/4) * (1/4) = 1/16.

Front

What is the probability of getting a red-green combo when spinning a spinner twice?

Back

If the spinner has equal sections for red and green, the probability of getting red first and green second is (1/4) * (1/4) = 1/16. The same applies for green first and red second, so the total probability is 1/16 + 1/16 = 2/16 or 1/8.
