Example Question #1 : Develop And Compare Probability Models And Find Probabilities Of Events: Ccss.Math.Content.7.Sp.C.7

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

 

Possible Answers:

Correct answer:

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.

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.
