For those teenagers who take the written driving test, only 80% have actually studied for it. Of those who study for the test, 60% pass. Of those who do not study for the test, 25% pass. A partially completed tree diagram illustrates the situation. Complete the tree diagram to help you find the decimal probabilities of all four outcomes.

Enter these probabilities as exact decimals. Do not round.

P(studies and passes test) =

P(studies and does not pass test) =

P(does not study and passes test) =

P(does not study and does not pass test) =
