Answer:

0.1175 or 11.75%

Step-by-step explanation:

If the new machine is 3 times more productive than the old machine, then 75% of widgets are produced by the new machine with a defective rate of 8%, while 25% of widgets are produced by the old machine with a defective rate of 23%.

The probability that a randomly chosen widget produced by the company is defective is given by:

[tex]P = 0.75*0.08+0.25*0.23\\P=0.1175=11.75\%[/tex]

The probability is 0.1175 or 11.75%.
