Total Number of Drivers : 17 +13 + 21 + 4 + 2 + 2 + 1 = 60
So, the median number of accidents per year should be between the 30th and the 31st driver
The 30th driver had committed 1 accident
The 31st driver had committed 2 accidents
The median = 1+2 /2 = 1.5 accidents per year
Option C

The 30th driver had committed 1 accident
The 31st driver had committed 2 accidents
The median = 1+2 /2 = 1.5 accidents per year

My answer is C.
Explanation:
If we list the given info in sequence we will be writing as 17 zeros, 13 ones, 21 twos etc.
Since there are 60 drivers (even no.), the median will come between 30th (n/2) driver sec. and 31st (n/2 + 1) driver sec. We can already see that starting at the zero end, the 30th driver will be in the ones section of the list, but the 31st driver will be in the twos section. Hence the median is 1.5.
Please post the ans.
