The probability of event a occurring is

\frac{5}{10}

. The probability of event b not occurring is

\frac{80}{100}

. Therefore, the probability that event a occurs while event…

What this question tests

Your ability to compute probabilities of single and compound events, including 'at least one' questions.

Forgetting to use the complement for 'at least one', or treating dependent events as independent.
