Select the Venn diagram that best represents the relationship between the following classes.
Prime numbers, Proper fractions, Even numbers
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) →
In a Venn diagram two circles overlap when some members belong to both classes, one circle lies inside another when every member of the first belongs to the second, and circles stay apart when the classes have no common member.
2 is both prime and even, 3 is prime but not even, and 4 is even but not prime, so the circles of prime numbers and even numbers overlap
A proper fraction (such as \(\frac{1}{2}\)) lies between 0 and 1 and is not a whole number, so it is neither prime nor even: its circle stays apart
Two overlapping circles and one separate circle, as in Option (1)
