 how would you diagnose a hardware system that was having excessive signal to noise problems from a camera that measures fluorescent signals? 1 Answer My first replies went to defining signal/noise in their situation (fluorescent imaging) , which was not the same as what I was accustomed to in semiconductors.

### Senior Data Scientist at Natera was asked...

 Imagine you have N pieces of rope in a bucket. You reach in and grab one end-piece, then reach in and grab another end-piece, and tie those two together. What is the expected value of the number of loops in the bucket? 2 Answers I got the correct answer, but the mathematician yelled at me for arriving to slowly at such an "easy" answer. The answer is as follows: Let f(N) be the expected number of loops given N ropes. Given one rope, the expected value is one loop: f(1) = 1. Adding a rope, there are two possible situations, either the first rope chosen is tied to itself or it is not. The probability of the first rope being tied to itself with N ropes is p(N) = 1/(2N -1). If the first rope is tied to itself, then the remaining ropes gives the same situation as the case with one fewer ropes and one loop at the beginning. If the first rope is not tied to itself, then no loops are added and we again have the N-1 rope case remaining. Therefore, we have a p(N) chance of having expected value 1 + f(N-1) and a (1-p(N) ) chance of having expected value f(N-1): f(N) = p(N)*(1+f(N-1) ) + (1-p(N) )*f(N-1) = p(N) + f(N-1) with base case p(N) = 1/(2N-1) we have: f(N) = sum{k = 1:N} (1/(2k-1)) e.g. f(2) = 1 + 1/3 = 4/3 f(3) = 1 + 1/3 + 1/5 = 23/15 f(4) = 1 + 1/3 + 1/5 + 1/7 = 176/105
