Exercise 4 Page 364

When calculating probability, we are comparing the number of favorable outcomes to the number of possible outcomes. To calculate the probability of rolling a 4 we will use the Probability Formula. P=Favorable Outcomes/Possible Outcomes On every side of a six-sided number cube we have a different number from 1 to 6. Therefore, rolling a six-sided number cube has 6 possible outcomes — one per each side. Out of 6 sides only 1 side has a number 4. We have only 1 favorable outcome. Now we have enough information to calculate P(rolling a 4). P=Favorable Outcomes/Possible Outcomes ⇓ P(rolling a 4)=1/6 The probability of rolling a 4 is 16, which can also be written as 1:6.
