Answer:
132
Step-by-step explanation:
there are 66 hands in party so we multi 2 by 66=132
We have
![y\in\{0,1,2\}](https://tex.z-dn.net/?f=y%5Cin%5C%7B0%2C1%2C2%5C%7D)
, and for each possible outcome we can determine the corresponding probability using the fact that
![X](https://tex.z-dn.net/?f=X)
is uniformly distributed among
![x\in\{0,1,\ldots,9\}](https://tex.z-dn.net/?f=x%5Cin%5C%7B0%2C1%2C%5Cldots%2C9%5C%7D)
.
![y=\begin{cases}0&\text{for }x\in\{0,3,6,9\}\\1&\text{for }x\in\{1,4,7\}\\2&\text{for }x\in\{2,5,8\}\end{cases}](https://tex.z-dn.net/?f=y%3D%5Cbegin%7Bcases%7D0%26%5Ctext%7Bfor%20%7Dx%5Cin%5C%7B0%2C3%2C6%2C9%5C%7D%5C%5C1%26%5Ctext%7Bfor%20%7Dx%5Cin%5C%7B1%2C4%2C7%5C%7D%5C%5C2%26%5Ctext%7Bfor%20%7Dx%5Cin%5C%7B2%2C5%2C8%5C%7D%5Cend%7Bcases%7D)
