Question

Tyler's family members choose numbers to assign chores.They each roll a six-sided number cube, and the personwho rolls the highest number selects first. The sides arenumbered 1 through 6. All sides are equally likely to berolled.What is the probability that Tyler rolls a number greater than 3?

Answer 1

Since all sides are equally probable, each number has probability equal to

`P(\text{side)}=(1)/(6)`

However, we need the probability for a number greater than 3. In this case, we have the sides equal to 4, 5 and 6. Then, the probabiblity is

`P(\text{side}>3)=3\cdot(1)/(6)=(3)/(6)`

Therefore, the answer is option A.
