Figure 1 shows how 25 people travelled to work.
Their travel to work is represented by the events
$$\begin{array} { l l }
B & \text { bicycle }
T & \text { train }
W & \text { walk }
\end{array}$$
- Write down 2 of these events that are mutually exclusive. Give a reason for your answer.
- Determine whether or not \(B\) and \(T\) are independent events.
One person is chosen at random.
Find the probability that this person - walks to work,
- travels to work by bicycle and train.
- Given that this person travels to work by bicycle, find the probability that they will also take the train.
