If nCk represents the number of ways k parts can be chosen from a pool of n, the probability of interest is the complement of the probability of selecting all good parts.
1 - (167C3)/(170C3) = 42,085/804,440 ≈ 0.0523
_____
nCk = n!/(k!(n-k)!)
its b
Step-by-step explanation:
cuz to sides are the exact same then one side is bigger than the others :)
I rounded each number to the nearest whole number and added those.
29 + 79 + 42 = 150
If you add the original numbers you would get 149.5, which rounds to 150.
The answer is a because if you divide 1000 by 2 you get 500 and the other ones you get a decimal.
