Answer
1/2
Work Step by Step
The problem asks you to find the probability of not stopping on red. You can find the answer by using the complement rules of probability.
The probability that an event E will not occur is equal to 1 minus the probability that it will occur.
P(not stopping on red)= 1-P(stopping on red)
Three out of six of the regions are red.
P(not stopping on red)= 1-3/6
Next, you have to find a common denominator.
P(not stopping on red)= 6/6-3/6
P(not stopping on red)= 3/6 OR 1/2 if reduced to lowest terms.
