In this challenge, we learn about geometric distributions. Check out the Tutorial tab for learning materials!
The probability that a machine produces a defective product is . What is the probability that the defect is found during the inspection?
The first line contains the respective space-separated numerator and denominator for the probability of a defect, and the second line contains the inspection we want the probability of being the first defect for:

5If you do not wish to read this information from stdin, you can hard-code it into your program.
Print a single line denoting the answer, rounded to a scale of decimal places (i.e., format).
