Exercise 1 Page 745

When calculating probability, we are comparing the number of favorable outcomes to the number of possible outcomes. To calculate the probability that a randomly chosen cube is red we will use the Probability Formula. P=Favorable Outcomes/Possible OutcomesIn the bag, there is a total of 6 red, 4 yellow, 3 blue, and 1 green cubes. The sum of these values is the number of possible outcomes. 6+4+3+1= 14 cubes Out of these, 6 are red, which is the number of favorable outcomes. Now we have enough information to calculate P(red).
P=Favorable Outcomes/Possible Outcomes
P(red)=6/14
P(red)=3/7
The probability of choosing a red cube is 37, which can also be written as 3:7.
