Final answer:
The mathematics problem involves finding two ages that multiply to 945, likely representing a grandmother and her grandson. Through factoring 945 and understanding reasonable age gaps, one can deduce the possible ages of the two individuals, keeping in mind generational life expectancies.
Step-by-step explanation:
The question pertains to finding the ages of a grandmother and a grandson whose ages multiply to 945. This is a mathematical problem that involves factors of the number 945. To solve this, one would need to list the pairs of numbers that multiply to 945 and determine which pair could reasonably represent the ages of a grandmother and a grandson.
It is important to note that the given information from the question about grandchildren being open to discussing sexuality with their grandmothers, although insightful on family dynamics, is not relevant to solving the mathematical problem at hand.
The other points labeled 'b' and 'c' mention probability and percentiles relating to the sum of ages, which seem to be part of a different set of mathematical problems unrelated to finding the specific ages of two individuals. Therefore, they will not be addressed in this answer.
By systematically examining the pairs of factors for the number 945, we can make an educated guess about which pair might represent the respective ages based on common life expectancies and generational gaps. For example, if 945 factored down to 15 and 63, one might conclude that the grandson could be 15 years old and the grandmother could be 63 years old.
