If 1 occurs 2y times, 2 occurs y times and 4 occurs 4y times, then find the mean for the following observations.

If 1 occurs 2y times, 2 occurs y times and 4 occurs 4y times, then find the mean for the following observations.

यदि 1, 2y बार, 2, y बार और 4, 4y बार घटित होता है, तो निम्नलिखित प्रेक्षणों का माध्य ज्ञात कीजिए।


Explanation (in simple text)

1 occurs 2y times → total = 1 × 2y = 2y

2 occurs y times → total = 2 × y = 2y

4 occurs 4y times → total = 4 × 4y = 16y

Total sum = 2y + 2y + 16y = 20y

Total number of observations = 2y + y + 4y = 7y

Mean = 20y / 7y = 20/7

🎯 Final Answer:

20/7
