Suppose 20% of all widgets produced at a factory are defective.

 

A simulation is used to model widgets randomly selected and then recorded as defective or working.

 

Which simulation best models the scenario?

 

 

 

A.    Place 100 equally sized pieces of paper in a hat. Of the 100, 5 read “defective” and the rest read “working”.

 

B.    Place 50 equally sized pieces of paper in a hat. Of the 50, 5 read “defective” and the rest read “working”.

 

C.    Place 25 equally sized pieces of paper in a hat. Of the 25, 5 read “defective” and the rest read “working”.

 

C.    Place 20 equally sized pieces of paper in a hat. Of the 20, 5 read “defective” and the rest read “working”.
