A small dairy plant packages milk into 1 litre cartons. The company uses an automated machine for filling the milk into the cartons. From past records it is known that 1 in 8 cartons that go through this machine are filled with less than 750 millilitres of milk. A random sample of 12 cartons that have gone through the machine is selected. 1.1. 1.2. State the precise random variable required to solve this problem using Binomial distribution. State 2 of the conditions necessary for a random variable to be modelled using a binomial distribution. 1.3. Find the probability that exactly two cartons are filled with less than 750 millilitres of milk. 1.4. Find the probability that none of cartons are filled with less than 750 millilitres of milk. 1.5. The machine will be recalibrated only if more than 3 cartons in the sample have less than 750 millilitres of milk. Find the probability that the machine will not need recalibration.
