Hello, could you please help me out with the following problem!

Using a tree diagram answer the following problem:

Vinnie is a researcher trying to develop a quick and accurate test for a new virus that is threatening to spread across the planet. He estimates that currently, 1% of the population has the virus. He has developed a test that detects the virus in those who have it 98% of the time. However, his test will also give a false positive 5% of the time. One day, Vinnie tries the test on himself, and it comes back positive. Given that he has tested positive, what is the probability that Vinnie actually has the virus
