Answer:
(a) 
(b) 
Step-by-step explanation:
Note that in this problem we have an initial population N = 50, of which 30 fulfill a certain characteristic "m" (belong to the second section). Then, from the population N, a sample of size n = 15 is selected and it is desired to know how many comply with the desired characteristic (second section).
So
Let X be the number of projects in the second section, then X is a discrete random variable that can be modeled by a hypergeometric distribution.
(a)
Therefore, to answer question (a) we use the following equation presented in the attached image:
Where:

Then:

(b)
For part (b) we have:


Answer:
First number:87
Second number:435
Third number:187
Step-by-step explanation:
First number=x
Seconded number=x•5
Third number=x+100
X+5x+(X+100)=709
7x+100=709
7x=609
87
