Problem 1152

Indicate whether the statement is true or false.

15 ϵ {2,7,12,20}




Thus, the statement 15 ϵ {2,7,12,20} means “15 is an element of set {2,7,12,20}”.

The elements of set A are 2, 7,12 and 20. Notice that 15 is not among the elements listed.

Thus, the statement “15 is an element of set {2,7,12,20}” is false.
