What is Theoretical Probability?

Back

Theoretical Probability is the likelihood of an event happening based on all possible outcomes, calculated using the formula: P(Event) = Number of favorable outcomes / Total number of outcomes.

What is Experimental Probability?

Back

Experimental Probability is the likelihood of an event happening based on the results of an experiment, calculated using the formula: P(Event) = Number of times the event occurs / Total number of trials.

What is the probability of NOT landing on a specific color if there are 8 colors on a spinner?

Back

The probability of NOT landing on a specific color is (Total sections - 1) / Total sections.

How do you calculate the probability of picking a vowel from the letters A, B, C, D, and E?

Back

Count the vowels (A, E) and divide by the total letters: P(Vowel) = 2/5.

What is the probability of selecting a non-red card from a deck with 18 red, 12 yellow, and 20 blue cards?

Back

P(Not Red) = (Total non-red cards) / (Total cards) = 32/50 = 16/25.
