Question

My professor gave our class a study guide for our midterm. On that study guide, there were 10 prompts he wanted us to know. Out of the 10, there were 3 prompts that I wasn't confident in. For the midterm, he picked 5 prompts out of the 10. Out of those 5 prompts, 3 of the prompts I wasn't confident managed to be on there. I want to know the probability of that happening.
If you could show the steps to solving it, that would be great.
