Answer and explanation:

Given : Candace rolled a 6-sided number cube 60 times and recorded the results in the graph.

We know,
$\text{Probability}=\frac{\text{Favorable outcome}}{\text{Total number of outcome}}$

To find :

a) According to the graph, what is the experimental probability of rolling a 5?

In the graph,

The number of rolls a 5 is 15.

Total number of rolls = 60

The probability is given by,

$\text{P(rolling 5)}=(15)/(60)$

$\text{P(rolling 5)}=(1)/(4)$

b) According to the graph, what is the experimental probability of rolling a 4?

In the graph,

The number of rolls a 4 is 5.

Total number of rolls = 60

The probability is given by,

$\text{P(rolling 4)}=(5)/(60)$

$\text{P(rolling 4)}=(1)/(12)$

c) What is the theoretical probability of rolling a 1?

The number of rolls a 1 is 1.

Total number of rolls = 6

The probability is given by,

$\text{P(rolling 1)}=(1)/(6)$

d) What is the theoretical probability of rolling a 3?

The number of rolls a 3 is 1.

Total number of rolls = 6

The probability is given by,

$\text{P(rolling 3)}=(1)/(6)$
