Suppose you just received a shipment of twelve televisions. Three of the televisions are defective. If two televisions are randomly selected, compute the probability that both televisions work. What is the probability at least one of the two televisions does not work? The probability that both televisions work is 0.545. The probability that at least one of the two televisions does not work is 0.455.

Suppose you just received a shipment of televisions. of fifteen the televisions are defective. If two televisions are randomly selected, compute the probability that both televisions work. What is the probability at least one of the two televisions does not work? The probability that both televisions work is nothing. (Round to three decimal places as needed.) The probability that at least one of the two televisions does not work is nothing. (Round to three decimal places as needed.)
