Answer:

Total number of people involved in the diagram = 81

n(AUB) = 73

n(CnB) = 2

Explanations:

a) Total number of people involved in the diagram = 45 + 11 + 8 + 10 + 3 + 2 + 2

Total number of people involved in the diagram = 81

b) Number of people in the set AUB

n(AUB) = 45 + 10 + 11 + 3 + 2 + 2

n(AUB) = 73

c) Number of people in the set CnB

n(CnB) = 2
