@alonsos I just put in an edit with proper formatting, just needs to be approved.

Well I apologize for the misunderstanding then. Thank you.

comment Average number of tries to reach 5 successes.
Good answer, though 'And a failed flip when n=0' is wrong, you may have not seen the edit, but if n=0, the flip always succeeds.

I've edited question to reflect that.

@AndréNicolas No, the lowest it goes is 0.

What do you mean.. residue?

What have you tried? Why do you think yes?

+1 for being clever. Hadn't thought of this.

comment The possible area of a triangle if three laterals of a triangle is between $0$ and $1$
Maybe i'm just thinking too simply, but isn't the max area when there are (all 3 sides) are 1?

comment Not understanding how to factor a polynomial completely
@Cherry_Developer No it should be: $P(x)=(2x-3)(2x+3)(4x^2+9)$

comment Probability of 7 Card Hand with All Different Ranks?
The first card is from 52, then subtract 4 each time? Just a thought but i think it would be: (52*48*44*40*36*32*28) should might be the top? The first card should still be included in the multiplication? Not that sure, but maybe this helped?

comment Intuitively, how do you explain the concept of Flux?
Could you possibly expand a bit more on this? I'm having a bit of trouble visualizing how it would work or a simple example of numbers or such?

Can you show the work which you've tried? and specifically where you got stuck when doing it?

@YvesDaoust I see, that makes sense.

comment Using the Chain Rule to prove trig derivatives
@YvesDaoust Really? Why? I've never seen the $\circ$ for my derivatives when doing them in class/examples.

comment Explaining Infinite Sets and The Fault in Our Stars
@Raskolnikov what you mean by "double" I mean, to me say, 0.1111.. and 1.1111... they seem to be inherently different numbers?

comment Explaining Infinite Sets and The Fault in Our Stars
This is above my understanding, but... it seems that there should be more between 0 and 2? From my sense.
