Question

A batch of 420 machined parts contains 10 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. Determine the range (possible values) of the random variable.

Answer 1

The range (possible values) of the random variable is {1,1,...411}

Step-by-step explanation:

The possible values are integers from 1 to 411 because 410 parts are conforming, a nonconforming part must be selected in 411 selections. This way, the range is {1,1,...411}
