Answer:
a

b

c

Step-by-step explanation:
Generally the size of the sample sample space is mathematically represented as

Where N is the total number of objects available and r is the number of objects to be selected
So for a, where N = 19 and r = 8



For b Where N = 25 and r = 3



For c Where N = 23 and r = 2



The point of intersection of these two lines is (2, 1)
The equation of a horizontal line that passes through the point (1, 1) is:
y = 1
The equation of a vertical line that passes through the point (2, 2) is:
x = 2
The point of intersection would be at:
x = 2, y = 1
The point of intersection of these two lines is (2, 1)
