This document contains 3 worksheets with math problems involving probability concepts like likely, unlikely, certain and equally likely outcomes. The problems ask students to identify the probability of drawing different colored marbles from a bag, choosing different types of cards from a deck, outcomes when spinning a spinner or rolling a dice. Students are asked to describe outcomes as likely, unlikely, certain or impossible. They must also determine the probability of different potential outcomes in various scenarios.
