    B)  \[\frac{4}{5}\]                       

    C)  \[\frac{12}{25}\]                               

    D)  \[\frac{1}{5}\]

    Correct Answer: B

    Solution :

    Shyam and Ekta are visiting a shop from Tuesday to Saturday. Total possible ways of visiting the shop by them \[=5\times 5=25\]. Possible ways of visiting the shop on same day = 5 Possible ways of visiting the shop on different days \[\text{=}25-5=20\] \[\therefore \] Probability of visiting the shop on different days \[=\frac{20}{25}=\frac{4}{5}\]
