 res2 rcnt: 0.0625
 res3 rcnt: 0.1875
 res4 rcnt: 0.125
 res5 rcnt: 0.0625
 res6 rcnt: 0.125
TOTAL rcnt: 1

$rcnt(r)={\frac {los(r)}{\sum _{r\in R}los(r)}}$

• r is a reservation in this share-with
• R is the set of all reservations in this share-with
• los is length of stay
• rcnt is room count

Binomial distribution

$P(n)={N! \over n!(N-n)!}p^{n}q^{N-n}$

• N: the fixed sample size
• p: the probability that one thing has the characteristic
• q: the probability that it doesn't (1-p)
