Consider the following. (Assume that the coins are distinguishable and that what is observed are the faces or numbers that face up.) Three coins are tossed; the result is at most one tail. What sets of elements are included in the sample space?

a)  

b)  

Step-by-step explanation:

From the question we are told that:

3 coin are tossed

Therefore

Sample space

Generally the sets that correspond with the result of at most one tail is therefore given as follows

Therefore

The result is at most one tail when

this doesn't make sense lol
