Since you already simplified it but made a mistake 2(7+4)+10(2x4)=2(11)+10(8)=22+80=102. So the answer is 102. Hope this helped.
Answer:
25π
Step-by-step explanation:

Answer:
Step-by-step explanation:
Note that .
Aha! We see a path to the solution!
We now know that our equation is actually .
We can divide both sides by to get .
By inspection or taking the logarithm base 2 of both sides, we see that .
So, the answer is and we're done!
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)!)
