asked • 04/10/24what is the probability that at least 1 of the 11 buyers will get a defective e-reader?
An electronics store receives a shipment of 26 e-readers. Unbeknownst to the store, 5 of the e-readers are defective. If the store sells 11 of these e-readers the first day, what is the probability that at least 1 of the 11 buyers will get a defective e-reader? (Round your answer to three decimal places.)

Probability of at least one of the buyers getting a defective e-reader = 1 - probability of none of the buyers gets a defective e-reader = 1 - (21/26)11 ≈ 90.46%
