Answer:
r/n
22.91%
33.33%
Explanation:
To calculate the experimental probability, we must divide the number of times the event occurred by the total number of events, that is: 
r / n 
r = 11, n = 48 
11/48 = 0.2291 
In other words, the experimental probability is 22.91% 
for the theoretical probability it would be the quantity that there is of that object among the total quantity of objects, in this case it would be: 
1/3 = 0.3333 
that is, the probability is 33.33%
