Exploring Probability in Compound Sample Spaces

The video tutorial explains a game show scenario where participants choose a vacation. It introduces the concept of sample space using a grid to list possible vacation outcomes. The tutorial then calculates the probability of selecting a vacation without snow for at least two days, assuming all outcomes are equally likely. The probability is determined by identifying outcomes that meet the criteria and dividing by the total number of outcomes.

What are the three possible types of vacations you can choose from in the game show?

• Island beach vacation, Ski vacation, City tour

• Island beach vacation, City tour, Camping

• City tour, Ski vacation, Camping

• Island beach vacation, Ski vacation, Camping

How many days can you choose to go on a vacation?

• One, Two, or Three days

• One, Three, or Four days
