Final answer:
The question is related to calculating probabilities and listing sample spaces in discrete probability distributions, suitable for a high school mathematics curriculum.
Step-by-step explanation:
The student's question involves the concept of sample spaces and the calculation of probabilities in discrete probability distributions, which is a topic covered in high school mathematics, particularly in the study of statistics and probability.
To answer exercise 85(a), listing the sample space means we need to enumerate all possible outcomes when drawing one card from the given set. With the cards well shuffled, the sample space consists of the eight cards: five green numbered 1-5 and three yellow numbered 1-3. Thus, the sample space is {Green1, Green2, Green3, Green4, Green5, Yellow1, Yellow2, Yellow3}.
