The problem asks you to find the probability of not stopping on 4. You can use the complement rules of probability to figure out your answer. The probability that an event E will not occur is equal to 1 minus the probability that it will occur: P(not E)= 1-P(E) The probability of stopping on 4 is 1/6. P(not 4)= 1-P(is a 4) P(not 4)= 1- 1/6 Next, you have to create a common denominator to subtract the two fractions. P(not 4)= 6/6-1/6 P(not 4)=5/6 The probability of not stopping on 4 is 5/6.
