From the question we know that if X denotes the number of abandoned cars on the road then E(X)=2.2 and that since this is discrete:

$\displaystyle

E(X)=\sum_{i=0}^{\infty}x_iP(X=x_i)=2.2$

and we want to find

$\displaystyle

P(X=0), P(X \geq 2)=1-P(X<2)$

But we dont know what type of distribution this is...any help would be appreciated.
