Electronics store received a shipment of 20 graphing calculators including eight that are defective four of the calculators are selected to be sent to a local high school how many of these selections will contain no defective calculator

 If it is probability, there is a 40% chance that a school will receive a defective calculator if the selections are random.

If the calculators are tested and sorted, there can be 3 selections of 4 calculators sent to schools once the 8 defective ones are removed.

Step-by-step explanation: The question is unclear.  Is it about subtracting the bad ones and dividing the good ones? Or is it about Taking chances with the selection of calculators to be sent?

If they subtract: 20-8= 12 left  12÷4= 3 sets of good ones.

If they take chances 8/20 = .4 so there is a 40% chance that a bad calculator will be included in the selection.
