IMO - E

As there are 8 people and 7 days in a week one day 2 or more than 2 people have to go to the hospital in order to satisfy the condition.

There are 7 days and 8 people. Thus, it's not possible to distribute them in such a way that on each day less than 2 people go to the hospital. Therefore, the probability that on at least one of the days, at least two people will go to the hospital is 1.
