An automobile manufacturer has discovered that 20% of all the transmissions it installed in a

particular style of truck one year are defective. It has contacted the owners of these vehicles and

asked them to return their trucks to the dealer to check the transmission. The Friendly Auto Mart

sold seven of these trucks and has two of the new transmissions in stock. What is the probability

that the auto dealer will need to order more new transmissions?
