Step 1 :The problem is asking to calculate the ratio of two permutations. The permutation formula is given by: \(_{n}P_{r} = \frac{n!}{(n-r)!}\) where \(n\) is the total number of items, \(r\) is the number of items to choose, and \(n!\) is the factorial of \(n\).
Step 2 :So, we need to calculate \(_{5}P_{2}\) and \(_{11}P_{4}\), and then divide the first by the second.
Step 3 :Calculating \(_{5}P_{2}\), we get 20.0
Step 4 :Calculating \(_{11}P_{4}\), we get 7920.0
Step 5 :Dividing the two results, we get a ratio of approximately 0.0025252525252525255
Step 6 :Final Answer: The ratio of the two permutations is approximately \(\boxed{0.0025}\)
