Using the probability concept, it is found that the number of desired outcomes that Taylor should use in her calculation is given by:
a. 3
A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, Taylor needs a number greater than 3, which for the dice are 4, 5 and 6, that is, 3 desired outcomes, hence option A is correct.
