Ok,
let no. of people in chalet when booking out = x
let C(n) be the statement that x^2+5=0
and since no. of people initially = 3,
let P(n) be the statement that x=(C(n.1).C(n.2))^1/2
Determining all possible combinations of n possible number of
people, p,
Since,
Therefore, let S(x) = total no. of people with respect to
np(1-p).n! no. of girls
* Given a subset U of A^n, when is U = V(I(U))?
* Given a set S of polynomials, when is S = I(V(S))?
Since, 
Therefore if n(1-p)=1/n!
Hence, deriving the value of x via L'Hopital's rule,
Therefore, x=25.2
Conclusion: no. of people in the chalet after that =3
