Hi am having trouble finding the lamda value for this question the below I tried different methods but they don't make sense. I know for everyone 25 metres theirs 1 nick.
A coil of wire has 500 metres of wire. Suppose there are 20 nicks (the most common problem with wire) are randomly distributed on a coil.
What is the probability that in a 50 metre length of wire there will be at least 4 nicks?
