What is theoretical probability?

Back

Theoretical probability is the likelihood of an event occurring based on the possible outcomes in a perfect scenario, calculated as the ratio of the number of favorable outcomes to the total number of possible outcomes.

How do you calculate the probability of an event?

Back

The probability of an event is calculated using the formula: P(Event) = Number of favorable outcomes / Total number of possible outcomes.

What is the probability of spinning an odd number on a spinner numbered 1 to 6?

Back

1/2, since there are 3 odd numbers (1, 3, 5) out of 6 total numbers.

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

Back

1/2, as there are 2 possible outcomes (heads or tails) and only 1 favorable outcome (tails).

If a spinner has 8 equal sections and 1 is yellow, what is the probability of NOT landing on yellow?

Back

7/8, since there are 7 sections that are not yellow.

What is the probability of spinning a red on a spinner with 5 equal sections, where only 1 section is red?

Back

1/5, as there is 1 favorable outcome (red) out of 5 total sections.

In a bag with 30 pieces of candy (15 grape, 7 cherry, 3 lemon, 5 strawberry), what is the probability of drawing a lemon?

Back

1/10, since there are 3 lemons out of 30 total pieces of candy.

What is the complement of an event in probability?

Back

The complement of an event is the probability that the event does not occur, calculated as 1 minus the probability of the event occurring.

What is the probability of drawing a cherry candy from the same bag?

Back

7/30, since there are 7 cherry candies out of 30 total pieces.

How does the concept of equally likely outcomes apply to theoretical probability?

Back

Equally likely outcomes mean that each outcome has the same chance of occurring, which is a key assumption in calculating theoretical probability.
