The set O represents the minimum temperatures, in degrees Fahrenheit, recorded in the city of Orlando in a year.

O = {49, 50, 50, 55, 56, 60, 65, 65, 70, 71, 72, 72}

The set T represents the minimum temperatures, in degrees Fahrenheit, recorded in the city of Tampa in a year.

T = {52, 54, 55, 59, 59, 61, 62, 68, 68, 70, 74, 75}

How many elements are in the set O ∪ T?

I believe the answer is 17, can someone clarify my answer?
