For each of the following exercises, determine if the random variable has a disc

Question

For each of the following exercises, determine if the random variable has a discrete uniform, binomial or none of these distributions. For the variables with discrete uniform or binomial, report the value(s) of parameter(s). There is a 2% chance to select a machined part that do not conform to customer requirements. The random variable is the number of parts in a sample of 5 machined parts that do not conform to customer requirements. Binomial n = 5, p = .2% There is a 2% chance to select a machined part that do not conform to customer requirements. Parts are selected successively, without replacement, until a nonconforming part is obtained. The random variable is the number of parts selected. The random variable is the moisture content of a lot of raw material. None of these distributions The first digit of a part's serial number is equally likely to be any one of the digits 0 through 9. One part is selected from a large batch and X is the first digit of the serial number.
