Question

3 persons are standing at the middle of edges of a triangle. All the 3 persons starts moving at same time with same speed in random direction what is the probability of meeting at least 2 persons?

Answer 1

No. of events will be 8. This is because the person can move either inside or outside the triangle.

And the no. of favorable events will be 6. This is because we want at least 2 person to meet and we have total 3 person, so 2x3 = 6

Probability = 6/8 = 3/4

Ans= 3/4
