Example 1Probability of Single Events
A box of counters in a maths lesson contains 2 yellow counters, 2 purple counters and 2 orange counters. One counter is taken at random. What is the probability that it is purple? Give your answer as a fraction in its simplest form.
Common mistake: Used the number of non-favourite items as the denominator
Correct Answer:1/31/3
Worked Solution:
There are 6 counters in total and 2 are purple, so the probability is 26\frac{2}{6} = 13\frac{1}{3}.
