How do you find the mode of the set {1, 2, 2, 3, 4}?

To find the mode of a set of numbers, you need to identify the number that appears most frequently. In this set, {1, 2, 2, 3, 4}, each number occurs the following number of times:

• The number 1 appears once.

• The number 2 appears twice.

• The number 3 appears once.

• The number 4 appears once.

Since the number 2 appears more frequently (twice) than any other number in the set, it is deemed the mode. Therefore, the correct answer is indeed 2, as it is the only number that has the highest frequency in the given set.
