2. Suppose that in a lot of 18 cars there are 6 blue cars. Suppose a sample of 4 cars is drawn and let ? =number of blue cars in the sample. a) If the sampling is done WITH replacement, determine if this is a binomial experiment using the 4 properties? b) If the sampling is done WITHOUT replacement, determine if this is a binomial experiment using the 4 properties? c) Assume the sampling is done WITHOUT replacement. i) Calculate the probability that there will be no blue cars in the sample. ii) Calculate the probability that there will be no more than 2 blue cars in the sample. iii) Calculate the expected number of blue cars in the sample.
