16 because 8 rooms have 8-11, 5 rooms have 4-7, and 3 rooms have 0-3 guests.
Step-by-step explanation:
The probability of not selecting green or yellow marble is equal to the probability of selecting red and blue marble
n(S) =17
n(A)=5 (red)
n(B)=6 (blue)
answer is 5+6/17
=11/17
Answer:
(p,r) = (1/3, 2/9)
Step-by-step explanation:
Here, we want to solve a system of equations
We can rewrite the second equation by dividing through by 2
So we have;
4p + 3r = 2
and
5p - 3r = 1
Add both equations:
9p = 3
p = 3/9
p = 1/3
Recall ;
5p - 3r = 1
3r = 5p - 1
Substitute the value or p here
3r = 5(1/3)-1
3r = 5/3 - 1
3r = 2/3
r = 2/9
So we have the solution set as;
(p,r) = (1/3 , 2/9)
Answer:
The real numbers are any number that corresponds to a point on the line Real and can be classified into numbers natural, whole, rational and irrational. In other words, any real number is between minus infinity and plus infinity and we can represent it on the real line .
