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
if it's a mix fraction, then you write 22 1/2. if improper fraction, then write 45/2
Okay
(Thanks for the points)
Like if the number is 4,359
You write 4 times 1,000+ 3times 100+ 5times 10+ 9 times 1
