Answer:
a) 0.70
b) 0.82
Step-by-step explanation:
a)
Let M be the event that student get merit scholarship and A be the event that student get athletic scholarship.
P(M)=0.3
P(A)=0.6
P(M∩A)=0.08
P(not getting merit scholarships)=P(M')=?
P(not getting merit scholarships)=1-P(M)
P(not getting merit scholarships)=1-0.3
P(not getting merit scholarships)=0.7
The probability that student not get the merit scholarship is 70%.
b)
P(getting at least one of two scholarships)=P(M or A)=P(M∪A)
P(getting at least one of two scholarships)=P(M)+P(A)-P(M∩A)
P(getting at least one of two scholarships)=0.3+0.6-0.08
P(getting at least one of two scholarships)=0.9-0.08
P(getting at least one of two scholarships)=0.82
The probability that student gets at least one of two scholarships is 82%.

Answer:
21.4% of 855=182.97
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 855 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 855 is 100%, so we can write it down as 855=100%.
4. We know, that x is 21.4% of the output value, so we can write it down as x=21.4%.
5. Now we have two simple equations:
1) 855=100%
2) x=21.4%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
855/x=100%/21.4%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 21.4% of 855
855/x=100/21.4
(855/x)*x=(100/21.4)*x - we multiply both sides of the equation by x
855=4.67289719626*x - we divide both sides of the equation by (4.67289719626) to get x
855/4.67289719626=x
182.97=x
x=182.97
now we have:
21.4% of 855=182.97
