Lesson: Mutually Exclusive Events

Comment on Mutually Exclusive Events

For the second example, if you select 7, 9, or 15 - both event A and B can occur together, no? Meaning they're NOT mutually exclusive. They're odd and less than 5. Please clarify! Thanks!

I believe you're referring to the example at 1:09 in the video.

Event A: the selected number is odd
Event B: the selected number is less than 5.

So, can events A and B occur at the same time? The answer is no. We cannot select a number that is odd AND is less than 5.

So, events A and B are mutually exclusive.

Your examples of 7, 9, and 15 are odd, but they are not less than 5.
