In a class of 21 students, 11 students passed the test. A total of 14 students completed their homework. If there are 4 students who did not pass the test AND did not complete their homework, what is the probability that a student passed the test GIVEN THAT they completed the homework?

Creating a two-way tables helps you visualize the problem. If you know that 11 people passed the test, then 10 people did not pass the test. 4 people didn't do their homework and didn't pass the test which means 6 people did the homework but did not pass the test. We also know that 14 students did their homework meaning that 14-6= **8 students did their homework and passed the test**.

Hope it helps!

It's a trademark I guess.

I have to give my answer some enthusiasm...

Your answers are usually pretty good.

That phrase is very common among the younger crowd, so it’s not a unique trade mark, but it is **always** irritating, and it’s **never** enthusiastic.

The enthusiasm should come from your answer not your valediction.

Maybe you could use a trademark similar to what CPhill uses . But don’t copy his.

Heureka uses this

Omi67 also uses

Asinus uses this !

Maybe you could use some combination of two or three emos that identifies you, but doesn’t distract from your answer.
