Two customers can visit the shop on two days in ways.
Hence total number of ways =36
(i) Two customer can visit the shop on any day of the week i.e.
MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY
Favorable number of ways = 6
We know that PROBABILITY =
Hence probability of the customer visiting the shop on the same day =
(iii) We know that sum of probability of occurrence of an event and probability of non occurrence of an event is 1.
Hence probability of the customer visiting the shop on the different day is
(ii) Two costumer can visit the shop in two consecutive days in the following ways:
(MONDAY, TUESDAY), (WEDNESDAY, THURSDAY), (THURSDAY, FRIDAY) (FRIDAY, SATURDAY)
Favorable number of ways =5
We know that PROBABILITY =
Hence probability of the customer visiting the shop on two consecutive days =
