Two customers Shyam and Ekta are visiting a particular shop in the same week (Tuesday to Saturday). Each is equally likely to visit the shop on any day as on another day. What is the probability that both will visit the shop on the same day?

If 4 people are chosen at random, then find the probability that no two of them were born on the same day of the week.

Two particles undergo SHM along the same line with the same time period (T) and equal amplitude (A). At a particular instant one is at x = -A and the other is at x = 0. They move in the same direction they will cross each other at. i) t = (4T)/3 " " ii) t = (3T)/8 " " iii) x = A/2 " " iv) x = A/(sqrt2)
