A supervisor of a packaging unit of a milk plant is being pressurized to finish the job closer to the distribution time, thus giving the production staff more leeway to cater to last minute demand. He has the option of running the unit at normal speed or at 110% of normal speed. He estimates that he will be able to run at higher speed 60% of time. The packet is twice as likely to damage at higher speed which would mean temporarily stopping the process. If a packet on a randomly selected packaging runs has probability of 0.112 of damage, What is the probability that the packet will not be damaged at normal speed ?
