The probability of scoring a total of 9 is 1/6, as there is only one combination of results (1 + 8) that add to 9.
What is probability?
Probability is the measure of how likely an event is to occur. It is expressed as a number between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain to happen. Probability can be used to make predictions and understand the likelihood of different outcomes. It is an important concept in decision making and risk assessment.
