Step-by-step explanation:
The Venn Diagram is attached
For number of people who saw a single movie only
See the number associated with the movie name excluding all intersection parts
For people who watched only 2 movies exactly
Sum all the intersection parts of any 2 circle parts=6+12+8=26
For total number of students surveyed
Sum up every number in the Venn diagram including the number 5 outside 3 circles(it represents that 5 people did not watch any of the films)
=7+12+10+6+4+8+8+5=60
