Step-by-step explanation:
The number of apples in a tree is a discrete data type. Discrete data refers to values that can only take on certain numerical values and cannot be measured or divided into smaller units. In this case, the number of apples can only be a whole number, such as 0, 1, 2, and so on. Discrete data often involves counting, and the values are distinct and separate from each other.
