Greg tossed a number cube and recorded the results. The table shows the number of times he rolled on each number, based on the table, what is experimental probability of rolling on a for the next toss?

1/6
1/8
2/9
1/9
Based on the data given in the table, the experimental probability of rolling a 4 on the next toss is 4 out of 36, which simplifies to 1/9. So the correct answer is 1/9.
To find the experimental probability of rolling a certain number on a number cube, you need to divide the number of times that number occurs by the total number of tosses.
Looking at the table, the frequency for rolling a 1 is 7. The total number of tosses recorded is the sum of all the frequencies, which is (7 + 5 + 6 + 4 + 8 + 6) = 36.
So, the experimental probability of rolling a 1 on the next toss is 7/36.
