2/81</h2>
Step-by-step explanation:
Probability is defines as the likelihood or chance that an event will occur.
Probability = expected outcome of event/total outcome.
Since a single die with 9 sides was rolled, the total event outcome will be 9*9 = 81
Expected outcome will be the event that the sum of the two rolls equals 3. The possible outcomes are {(1,2), (2,1)}. The expected outcome is 2
Probability that the sum of the two rolls equals 3 = 2/81
