Question

The random variable is the number of nonconforming solder connections on a printed circuit board with 970 connections. Determine the range (possible values) of the random variable.

Answer 1

Answer: X = {0,1,2,3,4,5,....970}

Explanation: Let  X → random nonconforming solder connections on a printed circuit board. The number has to be a whole number to indicate the connections. This gives all possible range of X = {0,1,2,3,4,5,....970}
