A dental hygienist randomly chooses a toothbrush for clients to take home after an appointment. He has two drawers to choose from. There are 29 toothbrushes in the first drawer, 7 of which are blue. In the second drawer, the dental hygienist has 20 toothbrushes to choose from but 7 of them are blue.
Based on the above information, does the dental hygienist have the SAME likelihood of choosing a blue toothbrush from each drawer? Why or why not?
No - because the TOTAL number of toothbrushes are different.
Although both drawers contain the same number of blue toothbrushes, the second drawer has less toothbrushes in total. The dental hygienist is more likely to randomly choose a blue brush from the second drawer compared to drawer one.
