Answer:

1. 20%

2. 45 %

3. 4 %

Step-by-step explanation:

In the attachment, I have drawn venn diagram.

From the venn diagram,

1. 20 % of people watches A and B but not C

2. The percentage of people watches exactly two programmes= 20+15+10 = 45 %

3. The percentage of people watches atleast one of the programmes

=17+12+14+20+10+15+8= 96%

$\therefore$ The percentage of people does not watch any one of the programmes= 100 - 96 = 4 %
