What terminology related to probability should second-grade students be familiar with before rolling dice?

The correct terminology that second-grade students should be familiar with before rolling dice includes "certain," "likely," "unlikely," and "impossible." These terms help students understand different outcomes of probability in relatable ways.

"Certain" indicates an outcome that will definitely happen, such as rolling a number between 1 and 6 when using a standard die. "Likely" refers to outcomes that have a good chance of occurring, such as rolling an even number on a die. "Unlikely" describes outcomes that are possible but not expected to occur frequently, like rolling a 7 with a single die, which is impossible. Lastly, "impossible" signifies events that cannot happen at all, like rolling a 0 on a standard die.

While some terms in the other choices sound relevant, they do not all accurately describe the range of probability in a way that is appropriate for second graders. Understanding these specific terms allows students to grasp basic concepts of chance and helps build a solid foundation for their future studies in probability and mathematics.
