George is not a very good computer technician. Each time that George tries to install a computer, there is only a 50% chance that the installation is completely successful. 30% of the time the installation is only partly successful and 20% of the time the computer is damaged beyond repair. George has been assigned 10 computers to install. What is the probability that exactly 7 computers are damaged beyond repair and only one installation is completely successful with 2 of the installations only partly successful?
