At 0:25, I say "We can't use the original probability formula, because there are no countable outcomes."

Hi Brent,

When you say or, do you mean union or intersection?

Many thanks

Hi Bartal,

A OR B can be thought of as the UNION of A and B

I'm doing a final reinforcement these days, my test will be in a week, before this, do you have any suggestions?

If you haven't taken many practice tests yet, I suggest you take some to work on your test-taking skills and to identify any remaining weaknesses to work on.
