What is the probability that both will visit the shop on: 1 the same day 2 different days 3 consecutive days
Asked by | 23 Feb, 2012, 06:57: PM
answered-by-expert Expert Answer

Since each person has 6 days to visit, so the total number combination of their visit is 6 × 6 = 36

Number of ways in which they visit on same day is 6 (MM, TT, WW, TT, FF, SS)

So, P(They visit on same day) = 6/36 = 1/6

P(They visit on different days) = 1 – (1/6) = 5/6

For consecutive days we have (MT, TW, WT, TF, FS) × 2 = 10

P(They visit on consecutive days) = 10/36 = 5/18
