Answer:
0.4
Step-by-step explanation:
These are the relative frequencies of each face (data are missing in the text of the problem):
Number Showing on Top Face Frequency
1 0
2 3
3 3
4 6
5 3
6 5
The probability to obtain a certain number when throwing the dice is given by
where
is the relative frequency of the number to occur
is the sum of the relative frequencies
Here the sum of the frequencies is:
For number 5 here, we have:
(from the table)
So the probability of getting a 5 is
For number 6 here, we have
So the probability of getting a 6 is
So the probability to obtain either a 5 or a 6 in the next rolling is:
