Final answer:
The student's statement is false; the total cups of sugar used can be calculated by multiplying the number of cups per batch by the number of batches. Moreover, the random variable X refers to the number of pies baked by Lee each day, which is used for statistical calculations.
Step-by-step explanation:
The statement, 'For each pie that she makes, she uses 3 cups of sugar' is false if we refer to the information provided in the example solution. To find the total number of cups of sugar needed, we calculate it based on how many batches she is making. If there are 3 cups in one batch and she is making 5 batches, the total cups needed would be 3 cups/batch × 5 batches = 15 cups.
Furthermore, the student's question seems to be related to probability and statistics, especially when defining a random variable X and the distribution for X, as well as finding the probability of an event (Lee baking more than 25 pies in a day). A random variable X refers to the number of pies Lee bakes every day.
