So you do 20%*426 to get 85.2 then you would subtract 85.2 from 426 because they sold 20% more than last year. On top of that the answer isn't 355 it is 340.8.
The probability of getting exactly zero tails is 1/8.
Step-by-step explanation:
When a fair coin is tossed three time, the set of equally likely outcomes is:
S= {HHH,HHT, HTH, THH, HTT, THT, TTH, TTT}
n(S)=8
Let A be the event that there are exactly zero tails which means there are all heads
Then
A= {HHH}
n(A)=1
![P(A)=\frac{n(A)}{n(S)}\\=\frac{1}{8}](https://tex.z-dn.net/?f=P%28A%29%3D%5Cfrac%7Bn%28A%29%7D%7Bn%28S%29%7D%5C%5C%3D%5Cfrac%7B1%7D%7B8%7D)
The probability of getting exactly zero tails is 1/8.

I believe the answer is b.
^ You again? Quit being sus and answer the question here instead of elsewhere.
To find the mean, all you have to do is add each number and then divide by how many numbers you added.
So, 38 + 29 + 16 + 42 + 33 = 158. There were five numbers added, so the next step is to divide 158 by 5. That equals 31.6 as your answer.
