Answer:
Poisson, as we have the mean number and not a proportion.
Step-by-step explanation:
We have the mean number of vehicle deaths per year, thus, since it is a mean and not a proportion, we use the Poisson distribution.
If we were working with the proportion of accidents that end in death for example, or any other proportion, it would be a binomial random variable.

Hope this helps!!!!!!!!!!!!
2x+3x=5x
the +10-10 cancel each other out so it's just 80
5x+80=180
5x=180-80
5x=100
x=20
