Oh, I didn't remember putting that in. I do have the power to control everything, though, so I could take that out.
I saw the first question posted was a math question posted by a guest (and answered by admin), and the one posted by Admin was also math. I didn't see many, but maybe I should check out more from that time.
It's not me downvoting you. Which Guest are you, Guest #1, Guest #2, or a guest I haven't met yet?
I just don't understand it well.
I do take AoPS, but it's only the beginning of the year. Counting and Probability is the last 10 weeks of class.
So is there, like, a formula or something to compute that?
You got it right!
I've got another question, though:
\(${16 \choose 4}$\)
What does that mean? There is no line to symbolize that it is a fraction.
maybe it's both guest #1. (I know that I am gullible to people older than me, I have 3 older cousins)
The one with the older looking guy is me at 7 years old. The one with the younger looking person is my brother dressed up for halloween 2017. Then there is a picture a landscape. If you saw all the slides, please don't spoil what is at the end.
and to you 2nd guest, you are probably also right, but the word gullible is probably written all over me, as I am only 11 and only got my account yesterday!
