Question

Let X = The number of defective watches in a sample of nine watches. List the values that the random variable X may assume and classify the random variable as finite discrete, infinite discrete, or continuous.

0,1,2,3,4,5,6,7,8,9; The random variable is finite discrete

0,1,2,3,4,5,6,7,8,9; The random variable is infinite discrete

X may assume the values of any positive integer. The random variable is infinite discrete.

X may assume the values of any positive integer. The random variable is continuous.

0,1,2,3,4,5,6,7,8,9; The random variable is finite discrete

0,1,2,3,4,5,6,7,8,9; The random variable is infinite discrete

X may assume the values of any positive integer. The random variable is infinite discrete.

X may assume the values of any positive integer. The random variable is continuous.

Explanation / Answer

Given that X = The number of defective watches in a sample of nine watches

X can be in integer only (watches cannotbe in fraction!) so it is discrete and countable and out on 9 watches none or all can be defective so the answer is:

0,1,2,3,4,5,6,7,8,9; The random variable is finite discrete
