A machine makes errors in a certain operation with probability p. There are two types of errors. The fraction of errors that are
type 1 is α, and type 2 is 1 - α.(a) What is the probability of k errors in n operations?(b) What is the probability of k1 type 1 errors in n operations?(c) What is the probability of k2 type 2 errors in n operations?(d) What is the joint probability of k1 and k2 type 1 and 2 errors, respectively, in n operations?
Normally you would divide something like this by the cuts made. So if there were cuts of 2 inches on a 10 inch rope, then you should divide 10 by 2. It's the same with this: Multiply by the reciprocal when you are dividing fractions.
