which set is infinite?
P = {positive numbers less than 60}
Q = {whole numbers between 10 and 20}
R = {intergers ge=reater than 18}
S = {even numbers between 5 and 15}
P, Q, R, or S
Jessica's answer is correct.
To find the answer, you would need to check if each set has a lower limit AND an upper limit. If both limits exist, and you're dealing with integers, the set is finite.
If one or both of the the limits is missing, the set is infinite.
