Problem

A pack contains 2020 cards numbered 11 to 2020. One card is drawn at random. a. (i) Identify and write the sample space SS. b. (ii) Let EE be the event that the number on the card is a multiple of 33 or 55. List the favourable outcomes for EE. c. (iii) How many outcomes are favourable to EE? d. (iv) Find the probability of the event EE.
Intuitive explanation

The core concept here is basic probability: finding the likelihood of a specific outcome when all outcomes are equally likely. The key insight is that probability is simply the ratio of favorable outcomes to total possible outcomes. Once you identify what you're looking for (your favorable cases) and count the total number of cards, the calculation becomes straightforward.
