please can you tell me how did you get the answer of it?


­Eight people have to go to the hospital during a particular week. What is the probability that on at least one of the days, at least two people will go to the hospital?

A. 0.2
B. 0.3
C. 0.7
D. 0.8
E. 1

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.
