Experimental probability
We want to find the number of rolls whose sum is more than 5.
In this case, the sum of each roll of the two numbers are:
We want to select the rolls whose sum is more than 5 (but not 5):
We have that the experimental probability is given by:
[tex]P(\text{ sum more than 5})=\frac{\text{number of rolls whose sum is more than 5}}{\text{total number of rolls}}[/tex]
There are 3 rolls whose sum is more than 5, and 7 is the total number. Then:
[tex]\begin{gathered} P(\text{ sum more than 5})=\frac{\text{number of rolls whose sum is more than 5}}{\text{total number of rolls}} \\ \downarrow \\ P(\text{ sum more than 5})=\frac{3}{7} \end{gathered}[/tex]
Answer: C. 3/7
