00:01 We are given in the question with data.

00:03 So, firstly, let us draw the vein diagram for the given data.

00:09 So, we are given with three types of social media platforms, that is facebook, that this represents facebook denoted by f and instagram, denoted by i, and linkedin, that is denoted by l.

00:28 So it is given in the question that 30 used all the three platforms, that is intersection of all the three is 30 and 90 use instagram, that is this call is 90 and 80 use linkedin, that is it is given as 80 and 120 use facebook.

00:54 And it is also given that 55 use both facebook and instagram that is it is given as 55 and 45 use both linkedin and facebook it is given as 45 and 45 use both instagram and linkedin so these are the given data let us complete the instagram as this is complete 55 that is facebook and instagram and both three are 30 so only using facebook and instagram will be 55 minus 30 that is this will be 25.

01:44 Similarly only using facebook and linkedin will be 45 minus 30 which is 50.

01:52 Similarly using linkedin and instagram and not facebook will be 50.

01:58 Now, using only linkedin will be 80 minus 15 plus 30 plus 50.

02:13 So it will be 20.

02:16 That is the person only using linkedin.

02:20 Similarly, only using instagram will be 90 minus 25 plus 30 plus 50 plus 15.

02:30 That is 20.

02:34 That is using only instagram is 20...
