.


Hello,


in your post,  wording part of the question 

<pre>
    If a randomly selected vehicle is red, &nbsp;what is the probability it is a truck?
</pre>

does not correspond to the symbolic part of the question

<pre>
    P(Red/Truck),
</pre>

because the symbolic part  &nbsp;" P(Red/Truck) " &nbsp;literally means

<pre>
    If a randomly selected vehicle is a truck, &nbsp;what is the probability it is red ?
