Exercise 8 Page 881

When calculating a probability, we are comparing the number of favorable outcomes to the number of possible outcomes. To calculate the probability of rolling a number greater than 1 on a die, we will use the Probability Formula. P=Favorable Outcomes/Possible Outcomes On the die there are 6 numbers. This is the number of possible outcomes. 1, 2, 3, 4, 5, 6 Furthermore, there are 5 numbers that are greater than 1. This is the number of favorable outcomes. 1, 2, 3, 4, 5, 6 Now we have enough information to calculate P(Greater than1).
