Please define your variable, we don’t want to guess what your variables mean. What is n(s) and n(E)?I think n(s)=2^16 because each one pass or die.
N(E)= 18C3

Can you answer the question @JayJay asked you? This will impact how you calculate your probability.Probability Formulas
Probability = (Number of a Favourable outcome) / (Total number of outcomes)
P = n (E) / n (S)
Where P is the probability, E is the event and S is the sample space. Now, let’s looks at some very common examples.
Can a player see, and therefore avoid, a panel broken by a previous player?
It sounds like a hypergeometric problem, have you learned about it?Yes next player see the result from previous player.
Absolutely no.It sounds like a hypergeometric problem, have you learned about it?
Thank you so much.For n people to cross, 16 - n need to fall. A player only falls when their step is broken, so if 16 - n players fall, 16 - n steps are broken in the end. The probability a step is safe or broken is always 1/2, so since there are 18 steps total the probability 16-n steps break and exactly n players cross is [math]\frac{ \binom{18}{16-n}}{2^{18}}[/math].
