What elements are necessary to determine the likelihood of winning both races?

To determine the likelihood of winning both races, understanding the probabilities of wins and losses is essential. This specific choice includes the crucial elements of the overall event: it considers not just past performance but also the probabilities associated with winning and losing.

When calculating the chance of multiple events happening together, such as winning both races, the individual probabilities of each race are necessary. By knowing the probability of winning each race, you can use the multiplication rule of probabilities to determine the combined likelihood of winning both. For instance, if you know the probability of winning the first race and the probability of winning the second race, you multiply these probabilities together to find the overall likelihood of winning both.

Other options, while they may contain some relevant information, do not fully address the requirement for calculating combined outcomes. Some may touch on parts of the scenario, but they lack the comprehensive detail needed for an accurate probability assessment.
