weight of a parcel shipped airborne
i dont know

Explanation:

• A continuous random variable can take on any value within a certain interval.
• Age of a person: Technically, age can be measured with infinite precision (e.g., 25.5 years, 25.55 years etc.). But in common - sense, when we say age, we often use whole - number approximations. However, in a strict mathematical/statistical sense (where we consider the concept of continuous random variables), it can be thought of as continuous.
• Number of students with a grade of A: This is a discrete variable because the number of students is a countable quantity (e.g., 5 students, 10 students).
• Color of someone's eye: This is a categorical variable, not a numerical (let alone continuous) variable.
• Weight of a parcel: Weight can take on any value within a range. For example, a parcel can weigh 1.5 kg, 1.55 kg, 1.555 kg etc. It is not restricted to only whole - number values and can be measured with arbitrary precision.

Answer:

Age of a person, Weight of a parcel shipped airborne
