Answer 1

Step-by-step explanation:

The total number of days from Tuesday to Saturday = 5

Hence, both of them can reach the shop in 5 ways.

So, total number of outcomes = 5 × 5 = 25 ways

They can reach on the same day in 5 ways, i.e.

(Tuesday, Tuesday) ; (Wednesday, Wednesday) ; (Thursday, Thursday) ; (Friday, Friday) ; (Saturday, Saturday) 

1) Probability of reaching the same day -

= 5/25 

= 1/5 

They can reach on consecutive days in following 8 ways :

(Tuesday, Wednesday) ; (Wednesday, Tuesday) ; (Wednesday, Thursday) ; (Thursday, Wednesday) ; (Thursday, Friday) ; (Friday, Thursday) ; (Friday, Saturday) ; (Saturday, Friday)

2) Probability of reaching on consecutive days -

= 8/25

3) Probability of reaching on different days -

As, Probability of reaching on same days = 1/5

Hence, probability of reaching on different days = 1 - 1/5 

= 4/5
