The forked line and probability methods make use of what probability rule?

test cross

product rule

monohybrid rule

sum rule

product rule

Explanation:

In Statistics, the product rule, also called the "Leibniz law", is a rule that allows the differentiation of products from differentiable functions. This rule says that the derivative of a two-function product is the first function times the derivative of the second function plus the second function times the derivative of the first function. This rule is often used in forked line and probability methods.
