Intro to Probability Flashcard

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.

Front

What is the theoretical probability of an event?

Back

Theoretical probability is calculated based on the possible outcomes in a perfect scenario, without any actual experiments.

Front

What is experimental probability?

Back

Experimental probability is calculated based on the actual results of an experiment, expressed as the ratio of the number of times an event occurs to the total number of trials.

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

Back

5/7

If a die is rolled 14 times, what is the experimental probability of rolling a 1 or 6 if it occurs 6 times?

Back

6/14

Front

How do you calculate the theoretical probability of pulling a red marble from a bag with 4 green, 3 red, 2 blue, and 1 yellow marble?

Back

Theoretical probability = Number of favorable outcomes / Total number of outcomes = 3/10.

Front

What is the expected number of tails when flipping a coin 100 times?

Back

50 times.

Front

What is the range of probability values?

Back

Probability can range from 0 to 1.

Front

What does a probability of 0 mean?

Back

A probability of 0 means that the event will not occur.

Front

What does a probability of 1 mean?

Back

A probability of 1 means that the event is certain to occur.
