Exploring Outcomes and Simple Probability

The video tutorial introduces the concept of probability, covering definitions such as experiment, outcome, sample space, event, and favorable outcomes. It provides examples of identifying and counting outcomes using letters and spinners. The tutorial explains simple probability, demonstrating how to calculate it using fractions, decimals, and percents, with examples involving spinners and a deck of cards.

What is an experiment in probability?

• A certain desired outcome

• A procedure with varying results

• A result that is certain to occur

• A set of all possible outcomes

What does the sample space represent?

• A specific desired outcome

• All possible outcomes of an experiment

• The likelihood of an event occurring

• The set of favorable outcomes

If a letter is chosen from the word 'basketball', what are the favorable outcomes for choosing the letter 'k'?

• b, a, s, e, t, l

• b, a, s, e, t

• a, s, e, t, l

• k
