Question

Question 12: - Two customers Shyam and Ekta are visiting a particular shop in the same week

(Tuesday to Saturday). It is equally likely to visit the shop on any day as on another day. What is

the probability that both will visit the shop oa) the same day?

b) consecutive days?​

Answer 1

Answer:

i) Possibility of visiting the shop on same day ={(tue,tue),(wed,wed),(thurs,thurs),(fri,fri),(sat,sat)}

Total outcomes is 5×5=25

P(on the same day) =  5/25=1/5

ii) Possibility of visiting the shop on consecutive days ={(tue,wed),(wed,thurs),(thurs,fri),(fri,sat),(thurs,wed),

(fri,thurs),(sat,fri),(wed,tue)}

Total outcomes is 25.

P(on consecutive days) =  8/25
