Which of the following diagrams shows the relationship between tall men, black-haired people and Indians?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) →
In a Venn diagram, two circles overlap when some members belong to both groups. Each pair of these groups shares members:
Some tall men have black hair, and some do not.
Some tall men are Indians, and many are not.
Many Indians have black hair, but not all, and many black-haired people are not Indian.
So every pair of circles must overlap, and a tall, black-haired Indian man belongs to all three groups at once. Only three mutually overlapping circles show this.
