Sure thing! Let me explain that part more clearly.
You can instead do exactly what you said and just sum up the lowest three categories: 10% + 5% + 2.5% = 17.5%, which is around 18%.
What I did was subtract the two cumulative sums: transmission + braking + steering = (electrical + engine + exhaust + fuel supply + transmission + braking + steering) - (electrical + engine + exhaust + fuel supply) = 100% - cumulative sum at point "fuel supply" = 100% - 82% = 18%.
I hope that helped you!

1. We are given a graph and asked how much do the 3 categories with the lowest and greatest frequencies account for the repairs.
2. Note that the frequencies strictly decrease in the graph when going from left to right. This means the 3 categories we're looking for are either all to the leftmost side or rightmost side.
3. The 3 categories having the greatest frequencies. To find how much they account for, we need to take their sum or the cumulative frequency at point "exhaust". This will be around 70%.
4. The 3 categories having the lowest frequencies. To find how much they account for, we need to take their sum or the difference of cumulative frequencies at points "steering" and "fuel supply". This will be 100% - around 82% = 18%.
Hello Can u pls explain more the language is little tough to understand also why are we taking 4 lowest frequencies wen asked for 3
