I roll a cube 50 times and got an even number 30 times. What is the relative
frequency (or experimental probability) of rolling an even number?

60%

Step-by-step explanation:

To do this you know that the cube was rolled 50 times and out of that 50, 30 were even.  So you set 30/50

30

= .6 then you set that to a percent simply getting 60%

50

I hope this helps :)

c. (3,2,6) is the answer.
