Simple 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, or as a percentage.

Front

What is the formula for calculating probability?

Back

Probability = (Number of favorable outcomes) / (Total number of possible outcomes)

Front

What is an even number?

Back

An even number is an integer that is exactly divisible by 2.

Front

How do you calculate the probability of spinning an even number on a spinner with numbers 1 to 8?

Back

There are 4 even numbers (2, 4, 6, 8) out of 8 total numbers, so the probability is 4/8 or 50%.

Front

What is the probability of choosing a letter other than 'A' from the word 'ALGEBRA'?

Back

There are 5 letters other than 'A' (L, G, E, B, R) out of 7 total letters, so the probability is 5/7.

Front

What is the probability of spinning a spinner and landing on blue if there are 3 blue sections out of 8 total sections?

Back

The probability is 3/8.

Front

How do you calculate the probability of selecting a brown candy from a bowl containing different colored M&Ms?

Back

Count the number of brown candies and divide by the total number of candies. For example, if there are 2 brown candies out of 20 total, the probability is 2/20 or 1/10.

Front

What does it mean to simplify a fraction in probability?

Back

Simplifying a fraction means reducing it to its lowest terms, where the numerator and denominator have no common factors other than 1.

Front

What is the probability of spinning a spinner and landing on 'A' if there is 1 'A' out of 4 total sections?

Back

The probability is 1/4.

Front

What is the difference between theoretical probability and experimental probability?

Back

Theoretical probability is based on the expected outcomes in a perfect scenario, while experimental probability is based on actual results from experiments.
