\(x^3+3x^2+3x+1=2\\ x^3+3x^2+3x-1=0\\ x\approx 0.26 \)

Not enough info given.

1 * 0.5 * 0.25 = 0.125

Check:

Number of paths = 4^3 = 64

Number of favourable pths = 4*2*1 = 8

8/64 = 1/8  = 0.125

Your right Builderboi, I was thinking of an octagon.

I let      p(x)=ax+b            and      q(x)=tx+r

I did all the substitution and got eall the terms in terms of b

I could then find q(-1) in terms of b  but not as a number on its own.

I do not think that my answer is wrong. 

\(a=\frac{3-b}{2}\\ t=\frac{8}{3-b}\\ r=\frac{34-2b}{b-3}\\ \)

etc

2 * 0.5^6 - 0.5^7 =  0.0234375

0

It cannot land back at point A, not after 3 moves

I dont know what 'total turns' means but if the first and second ones loses on their first and second go then the game is over. so that is 5 goes in total.

6 on top

6 in top section

6 in bigger sections

that is 18

it is correct.
