DeVry MATH 221 Week 4 Discussion Latest

Please keep these 2 statements in mind as we study random variables.

For today’s post please give an example of a discrete random variable.

eg.

If I have 8 cans of coca cola in my refrigerator, that’s a discrete random variable — I can count them.

But, if I say that I have 12 ounces in each can, that’s continuous because that’s a measurement. And I can’t really say that it’s 12 ounces. It might be 12. 1 or 11.9 or it could even be 12.05 or 11.95. Getting more accurate it could be 12.00001 or 11.99999. And that’s why we call it continuous — on the number line I can always get a little closer than I was a moment ago.
