3. The table below shows the transport options, usual travel times, possible delay times and corresponding probabilities of delay for a journey. All times are in minutes.
| Transport option | Usual travel time | Possible delay time | Probability of delay |
| \multirow{2}{*}{Car} | \multirow{2}{*}{52} | 10 | 0.10 |
| | 25 | 0.02 |
| \multirow{2}{*}{Train} | \multirow{2}{*}{45} | 15 | 0.05 |
| | 25 | 0.03 |
| \multirow{2}{*}{Coach} | \multirow{2}{*}{55} | 5 | 0.05 |
| | 15 | 0.01 |
- Draw a decision tree to model the transport options and the possible outcomes.
- State the minimum expected travel time and the corresponding transport option indicated by the decision tree.
