You roll a standard number cube 8 times. The results are {5,1,2,4,6,3,5,5}. Find the experimental probability of P(rolling a 6). Write your answer as a fraction in the following form n/d (no spaces).

(a)  

2.

You roll a standard number cube 8 times. The results are {5,1,2,4,6,3,5,5}. Find the experimental probability of P(rolling an even number). Write your answer as a fraction in the following form n/d (no spaces).

3.

You roll a standard number cube 8 times. The results are {5,1,2,4,6,3,5,5}. For the next 60 rolls, predict the number of rolls that will result in a multiple of 3 (3 or 6). Write your answer as a fraction in the following form n/d (no spaces).
