Best answer

The correct option is: (B) 4/5

Explanation:

Shyam and Ekta are visiting a shop from Tuesday to Saturday. 

Total possible ways of visiting the shop by them = 5 x 5 = 25

Possible ways of visiting the shop on same day = 5 

.'. Possible ways of visiting the shop on different days = 25 - 5 = 20 

.'. Probability of visiting the shop on different days = 20/25 = 4/5
