Two customers are visiting a particular shop in the same week (monday to saturday). Each is equally likely to visit the shop on any one day as the other. what is the probability that both will visit the shop on the
Total number of days = 6
first customer can visit any day (between monday to saturday)i.e. 6 days
second customer can also visit any day (between monday to saturday)i.e. 6 days
therefore total number of ways to visit the shop by two customers = 6×6=36 ways
if they visit the shop same day.
so number of ways to visit the shop on the same day is 6 ( any day between Monday and Saturday)
Probability of visiting the shop on different day = 1 - probability of visiting the shop on same day
3.. if they visit the shop on consecutive day, following cases are possible
so we have 5 pair of days, in which they can visit. since there are 2 different customers, it can be done in 2 ways.
so total no of ways when they can visit in consecutive days =5×2=10
hence the required probability =
