Answer:
i do not know
Step-by-step explanation:
well first off u didn't give the graph at all which makes it impossible to answer.
To transform a mixed number to an improper fraction, we must multiply the denominator by the large number, and add the numerator.
So for
: 
But we also put this over the denominator in the mixed number, so we get:
.
Then we do the same for
:

Then we must find a common denominator. Let's use 21 (multiply 3 and 7):


Now that we have a common denominator, we can subtract across:

Since
cannot be reduced any further, we are going to leave this as our answer.
So the answer is
.
Answer:
a) 
b) 
Step-by-step explanation:
Number of balls in the urn = 12
Number of white balls in the urn = 4
So, number of balls which are not white = 12 - 4 = 8
We know that probability = No. of outcomes/Total number of outcomes
Let
denotes the event of getting white ball by A, B and C
a) each ball is replaced after being drawn.
Probability = Number of white balls/Total number of balls
Solution: 
b)the balls that are withdrawn are not replaced.
Solution:
If A wins: 
If A lost and B wins: 
If A and B lost and C wins: 
and so on....
Step-by-step explanation:
3x+12=45
3x=45-12
3x=33
3x/3=33/3
x=11
