Hi, in the given problem it is given that there are total of 42 students.
00:05
So, we have total 42 students and out of them some of them are taking history.
00:15
So, history is taken by 22 students and biology are taken by total of 17 students and the number of students that are taking both history and biology, h is for history and b is for biology.
00:36
So, that is 8.
00:38
So, now we are required to find the number of students who are taking biology but not history.
00:44
So, for that we will be drawing a venn diagram.
00:47
So, this is the venn diagram.
00:49
Now, here we can see that let's say this is for history h, this is for biology.
00:55
Now, it says that both of both history and biology are taken by 8.
01:01
So, this is common here.
01:02
So, that would be 8.
01:03
Now, history is the left of the people are just taking only history...
