Rhianna has 12 assignments left to complete for online learning this week. 5 of them are for statistics, 4 of them are for earth & space science, and the rest of them are for economics.

Answer:

1/22

Step-by-step explanation:

let me know if i got this wrong, but the events are dependent, so the equation   is (5/12)(4/11)(3/10)= 1/22.

Since there are 5 statistic and 12 total, that's obviously the first fraction. Then you take one from each because both sides are getting smaller (less statistic assignments and less total assignments.)

I did just learn this, but let me know if I was wrong please.
