Hi. Thanks for your question!

Here's an example of a real-world probability problem.

In my city there's typically a baseball game 2 days out of 5. If there's a ball game, it takes me over an hour to get home from work 70% of the time. If there's no ball game, it takes me over an hour to get home from work 20% of the time. On any given day - without knowing the game schedule - what's the probability that it'll take me over an hour to get home from work?

And the solution:

40% chance of a baseball game * 70% probability = 0.28
60% chance of no baseball game * 20% probability = 0.12

Adding them together, using the addition rule, gives 0.40%

So in general there's a 40% chance of a long commute.

Kind regards,
Susan
