Answer:
B
Step-by-step explanation:
Experimental probability is the ratio of the number of times an event occurs to the total number of trials or times the activity is performed.
A number cube is rolled 10 times, so
<u>Number of trials or times the activity is performed</u> = 10.
An even number comes up 6 times, so
<u>Number of times an event occurs</u> = 6.
Hence, the experimental probability is
![P=\dfrac{6}{10}=\dfrac{3}{5}.](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7B6%7D%7B10%7D%3D%5Cdfrac%7B3%7D%7B5%7D.)
