Question

3 people A, B and C are sitting in a circular fashion. Find the probability that A and B do not sit together.

• A. 0
• B. $\frac{1}{2}$
• C. $\frac{1}{3}$
• D. 1

Answer 1

The correct option is A

0

Let us draw the figure of their seating arrangement.

Since they are seated in circular fashion, the order does not matter and hence A, B and C will always sit next to each other.

$\therefore$ probability that A and B will not sit next to each other will be 0.
