Question

The table shows the result of rolling a number cube several times.


Two row table. First row values are Outcome, 1, 2, 3, 4, 5, 6. Second row values are Number of times outcome occurred, 4, 5, 5, 5, 4, 7.


To the nearest percent, what is the experimental probability of rolling a 2 or a 5?



A.
9%


B.
23%


C.
30%

Answer 2

What is the total number of rolls of the number cube?

Answer 3

Answer 4

To find the total number of rolls of the number cube, you need to add up the numbers in the row labelled "Number of times outcome occurred". Can you do that?

Answer 5

4 + 5 + 5 + 5 + 4 + 7 = ?

Answer 6

For the next step you add the number of times a 2 was rolled to the number of times a 5 was rolled:
5 + 4 = 9
Then the required percentage 'the experimental probability of rolling a 2 or a 5 is given by:
\[\frac{9}{(4+5+5+5+4+7)} \times\frac{100}{1}=you\ can\ calculate\]
