How can the odds of a certain event be calculated using the Product Law?

The correct answer emphasizes the application of the Product Law, which states that the probability of two or more independent events occurring together can be found by multiplying their individual probabilities.

In genetics, this principle is particularly useful when calculating the probabilities of multiple traits being inherited. For instance, if you want to determine the likelihood of acquiring two independent traits, you would calculate the probability of each trait occurring separately and then multiply those probabilities together to find the combined probability of both traits occurring simultaneously.

This method leverages the nature of independent events, where the outcome of one event does not affect the outcome of another. An example would be determining the probability of a plant showing both tall stature and yellow seeds if each trait follows independent inheritance patterns.

The other options do not accurately reflect the methodology related to calculating event probabilities using the Product Law. Adding probabilities may be relevant when considering mutually exclusive events, while assessing genetic relationships or determining the total number of traits involved addresses different aspects of probability and genetics that are not specifically aligned with the Product Law.
