A poll was taken of 100 students at a commuter campus to find out how they got to campus. The results were as follows:
29
said they drove alone.
36
rode in a carpool.
36
rode public transportation.
6
used both carpools and public transportation.
4
used both a carpool and sometimes their own cars.
6
used buses as well as their own cars.
1
used all three methods.
How many used none of the above-mentioned means of transportation?
. students
To find out how many students used none of the mentioned means of transportation, we need to calculate the total number of students who used any means of transportation and subtract it from the total number of students surveyed.
The given information provides the number of students who used each means of transportation, but it doesn't mention anything about students who didn't use any of the mentioned means.
To find the number of students who used none of the mentioned means of transportation, we first need to calculate the total number of students who used at least one of the mentioned means. We can add the number of students who used each means together:
Total number of students who used at least one means = 29 (drove alone) + 36 (carpool) + 36 (public transportation) + 6 (carpool and public transportation) + 4 (carpool and own car) + 6 (bus and own car) + 1 (all three methods)
= 118 students
Next, we subtract this total from the total number of students surveyed, which is given as 100:
Number of students who used none of the mentioned means of transportation = Total number of students surveyed - Total number of students who used at least one means
= 100 - 118
= -18
Since it is not possible to have a negative number of students, we can conclude that there was an error either in the given information or in the calculations. Please double-check the data provided or the calculations used to find a more accurate answer.
