Number of days they can visit =5
Total number of ways they visit=5*5=25
(1) favourable outcomes = 5
( as both can visit on Tue, wed, thru, Fri, sat)
probability =5/25=1/5
(2)ways can be like (tue, wed)(wed, thru)(thru, Fri) (Fri, sat)
each pair has 2 ways as both can change their day with each other
So, total number of ways= 8
Probability =8/25
(3)fav. ways= total ways - same day ways
=25-5=20
Probability = 20/25=4/5
