From Intro to Statistics - Probability Homework
Question:
A bag contains two pencils, one ruler, and five pens. What is the probability of randomly selecting a pen, a ruler, and a pencil without replacement? Round your answer to 3 decimal places.
(For my first attempt, the answer I got was 0.01953125, rounded to 0.020. This answer was wrong. The question was fill in the blank, not multiple choice. It doesn't give you the correct answer. You just know whether you got it right or not. You get three attempts total.)
