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

Brainliest please, I need 4 more :P
