Simple Theoretical Probability

Front

What is theoretical probability?

Back

Theoretical probability is the likelihood of an event occurring based on all possible outcomes, calculated as the number of favorable outcomes divided by the total number of outcomes.

Front

How do you calculate the probability of an event?

Back

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

Front

What is the probability of spinning a number that does not exist on a spinner?

Back

The probability is 0, as there are no favorable outcomes.

Front

If a number is randomly selected from 0-10, what is the probability of selecting a number greater than 5?

Back

The probability is 5/11, as there are 5 favorable outcomes (6, 7, 8, 9, 10) out of 11 possible outcomes.

Front

In a bowl with 4 yellow, 6 orange, 3 green, 5 blue, and 2 brown M&Ms, what is the probability of selecting a brown candy?

Back

The probability is 1/10, as there are 2 brown candies out of a total of 20 candies.

Front

What is the probability of selecting an orange candy from the same bowl?

Back

The probability is 30%, as there are 6 orange candies out of 20 total candies.

Front

What is the probability of drawing a black ace from a standard deck of 52 playing cards?

Back

The probability is 1/26, as there are 2 black aces (spades and clubs) out of 52 cards.

Front

What does it mean if the probability of an event is 1?

Back

It means the event is certain to occur.

Front

What does it mean if the probability of an event is 0?

Back

It means the event is impossible and cannot occur.

Front

If a spinner has 8 equal sections numbered 1 to 8, what is the probability of spinning a 3?

Back

The probability is 1/8, as there is 1 favorable outcome out of 8 possible outcomes.
