Answer:
(a) 2,481,115 ways
(b) 1 way
(c) 2,572,999 ways
Step-by-step explanation:
a = we select 3 units from 250-3 = 247 nondefective units.
b = since there is a different order of the units that will lead to the same units being selected, the order isnt actually important and therefore we really just need to use a combination. We have to select 3 unis from 3 defective units.
c = we select 3 units from 250 units
