Explanation
For probability questions, always begin by separating out the probabilities of each individual event. Then, if all the events happen (an “and question”), multiply the probabilities
together. If only one of the multiple events happens (an “or question”), add the probabilities together.
In this case, there are two events: rain on Monday and rain on Tuesday. The question asks for the probability that it will rain on Monday and on Tuesday, so multiply the individual probabilities together:
\(\frac{1}{6}\times\frac{1}{6}\).
