Question

Andrew goes to the school by bus.

The probability that the bus is late is 0.1.

If the bus is late, the probability that the Harris is late to the school is 0.8.

If the bus is not late, the probability that Andrew is late to school is 0.05.


i) Draw a tree diagram to show the above information with all the probabilities.

Answer 1

Answer: I am not able to create images such as tree diagrams. But I can explain to you how it could be done.

A tree diagram is a visual representation of the possible outcomes and their probabilities.

The tree diagram to show the above information would have two branches: one representing the event that the bus is late and the other representing the event that the bus is not late.

The first branch, "Bus is Late", would have a probability of 0.1 and would split into two further branches: one representing the event that Andrew is late to school (with a probability of 0.8) and the other representing the event that Andrew is not late to school (with a probability of 0.2).

The second branch, "Bus is not Late", would have a probability of 0.9 and would split into two further branches: one representing the event that Andrew is late to school (with a probability of 0.05) and the other representing the event that Andrew is not late to school (with a probability of 0.95).

This tree diagram will help you to understand the relationship between the different events and their probabilities, as well as the overall probability of Andrew being late to school.
