Answer: 10 out of 2000 (1/200)
Step-by-step explanation:
Sure it says that 10 people in a group (including Neil) bought 10 tickets each but that isn't what the question is asking. It is only considering Neil.
Think of the question this way. What is the probability Neil won a raffle is 2000 tickets are in total and Neil bought 10.
10 tickets are the tickets Neil bought and 2000 tickets is the total
10 on top and 2000 on the bottom.

Answer:
x = 65
Step-by-step explanation:
The sum of exterior angles of a polygon is 360°.
40 + x + 77 + 2x + 45 = 360
3x + 165 = 360 . . . . simplify
x + 55 = 120 . . . . . . divide by 3
x = 65 . . . . . . . . . . . subtract 55
Let
![P(x)=ax^2+bx+c](https://tex.z-dn.net/?f=P%28x%29%3Dax%5E2%2Bbx%2Bc)
. You have derivatives
![P'(x)=2ax+b](https://tex.z-dn.net/?f=P%27%28x%29%3D2ax%2Bb)
and
![P''(x)=2a](https://tex.z-dn.net/?f=P%27%27%28x%29%3D2a)
. Then
![\begin{cases}P(2)=4a+2b+c=5\\P'(2)=4a+b=3\\P''(2)=2a=2\end{cases}](https://tex.z-dn.net/?f=%5Cbegin%7Bcases%7DP%282%29%3D4a%2B2b%2Bc%3D5%5C%5CP%27%282%29%3D4a%2Bb%3D3%5C%5CP%27%27%282%29%3D2a%3D2%5Cend%7Bcases%7D)
From the last equation, you have
![a=1](https://tex.z-dn.net/?f=a%3D1)
. Plug this into the second equation to get
![4+b=3\implies b=-1](https://tex.z-dn.net/?f=4%2Bb%3D3%5Cimplies%20b%3D-1)
. Plug these into the first to get
![4-2+c=5\implies c=3](https://tex.z-dn.net/?f=4-2%2Bc%3D5%5Cimplies%20c%3D3)
.
So the polynomial is
