What I Know (Pre-Test) Before we begin with our lesson, you need to answer the pre-test honestly to check your background knowledge of the topic on this module. Directions Read each stem carefully and choose the letter of the correct answer. Write the chosen letter on a separate sheet of paper. 1. Which describes an experiment? A teasing a coin C. choosing a marble from a jar D. all of the above B rolling a single die 2. Which is an event? A rolling a pair of dice B. picking a yellow-colored marble C. drawing letter cards from a box D. flipping of coins 3. What is an experimental probability? A. Experimental probability of an event is the number of times the event occurs. B. Experimental probability of an event is equal to the total number of trials. C. Experimental probability of an event is the ratio of the number of favorabile outcomes to the total number of trials. D. Experimental probability of an event is the ratio of the total number of trials to the number of times the event occurs. For numbers 4-5.
