Compound Probability and Number Cubes

The video tutorial focuses on solving a standardized math test question involving compound probability. It explains the problem of rolling a number cube twice and finding the probability that the sum of the numbers rolled is eight. The tutorial uses a tree diagram to illustrate the sample space and demonstrates how to calculate the probability by identifying the successful outcomes. The solution is determined to be 5 out of 36 possible outcomes.
