## Example Questions

### Example Question #861 : Grade 7

If John were to roll a die times, roughly how many times would he roll a or a       Explanation:

A die has sides, with each side displaying a number between Let's first determine the probability of rolling a or a after John rolls the die a single time.

There is a total of sides on a die and we have one value of and one value of ; thus, our probability is: This means that roughly of John's rolls will be a or a ; therefore, in order to calculate the probability we can multiply by —the number of times John rolls the die. If John rolls a die times, then he will roll a or a roughly times.

If John were to roll a die times, roughly how many times would he roll a       Explanation:

A die has sides, with each side displaying a number between Let's first determine the probability of rolling a after John rolls the die a single time.

There is a total of sides on a die and only one value of on one side; thus, our probability is: This means that roughly of John's rolls will be a ; therefore, in order to calculate the probability we can multiply by —the number of times John rolls the die. If John rolls a die times, then he will roll a roughly times.
