Hey, I'm looking at this code of yours: \binom{5}{4}$$\frac{1}{2}$$^5=\frac{5}{32} So the "binom" is automatically making a fraction and putting parenthesis around it right? (I got annoyed that my right parenthesis was a single-line instead of the double-height for a fraction, and had to go edit it to fix it.) And you've got \'s in front of both the left and right parenthesis of the middle fraction. Is that doing the same thing as "\left" and "\right"???

I always preview my post to make sure. \binom{n}{r} doesn't make a fraction, it produces the binomial coefficient nCr(n,r) : $\binom{n}{r}$ (notice there is no bar).

I couldn't make that work. Hmm, maybe I'll just stick with what I already know.

Sorry, I didn't mean a fraction - I just meant setting it top and bottom. Listen to what I'm meaning, not what I'm saying!

Read the article I posted a link to and your textbook, it will become obvious then. You will see the beautiful relationship between the binomial theorem and binomial probability...it is unavoidable.

Thank you so much, Mr.MarkFL... You're my best teacher ever
