Exercise 2 Page 717

When calculating probability, we are comparing the number of favorable outcomes to the number of possible outcomes. To calculate the probability that a multiple of 3 is rolled on a 6-sided die, we will use the Probability Formula. P=Favorable Outcomes/Possible Outcomes When rolling a 6-sided die, there is a total of 6 possible outcomes. Out of these, there are 2 numbers we could roll that are multiples of 3. These are our favorable outcomes. Now we have enough information to calculate P(multiple of3).

P=Favorable Outcomes/Possible Outcomes

SubstituteValues

Substitute values

P(multiple of3)=2/6

ReduceFrac

a/b=.a /2./.b /2.

P(multiple of3)=1/3

The probability of rolling a multiple of 3 is 13, which can also be written as 1:3.
