A software engineer creates smartphone applications as a hobby, yet bugs/glitches occur occasionally in the applications they create.
The probability of a random application having a bug/glitch is 0.03. Assume all applications are independent. (Round your answers to
4 decimal places, if needed.)
(a) What is the probability that the 3rd application created is the first to have a bug/glitch?
(b) What is the probability that less than 4 applications are created to produce the first one with a bug/glitch?
(c) If the engineer has already created four applications with no bug/glitch, what is the probability that the 12th application created is
the first to have a bug/glitch?
(d) What is the mean number of applications created to produce the first one with a bug/glitch? What is the corresponding standard
deviation?
