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
 is the relative frequency of the number  to occur
 to occur
 is the sum of the relative frequencies
 is the sum of the relative frequencies
Here the sum of the frequencies is:

For number 5 here, we have:
 (from the table)
 (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:

 
        
             
        
        
        
Answer:
370
Step-by-step explanation:
The venn diagram corresponds to students who were sick in January at a Chicago high school.
Students who had only fever= n(A) = 80
Students who had only headache= n(B) = 90
Students who had only cough  = n(C) =60
Students who had both cough and fever = n(AC) = 10
n(AB) = 40:n(BC) = 30  n(ABC) = 20
Hence total students = 800
no of students who were absent due to other reasons = 100
REmaining students = 700
Students who were sick = sum of all =330
So no of students who were at school = 700-330 = 370

Answer: Distance between O and the line 1 is 3 inches.
Explanation:
Since we have given that 
Distance between point A and the line 1 = 10 inches
Distance between point B and the line 1 = 4 inches
Total length of segment AB is given by

Since O is midpoint of the line segment AB.
so, AO is given by

Now, Distance between O and the line 1 is given by

Hence, Distance between O and the line 1 is 3 inches.
