From a sample of 200 software engineers, determine the ratio of those proficient in Python to those proficient in Java using the given information:Category Number Proficient in Python and Java 50 Proficient in Python only 70 Proficient in Java only 60 Proficient in neither language 20
12:11
Step 1 – Total proficient in Python: Python only + Both = \(70 + 50 = 120\).
Step 2 – Total proficient in Java: Java only + Both = \(60 + 50 = 110\).
Step 3 – Ratio Python : Java = \(120 : 110 = 12 : 11\).
Hence, the correct answer is 12 : 11.
