Answer

$\frac{13}{2500}$

Work Step by Step

There are $10,000$ items produced in total, out of which $52$ are defective. We know that the formula for the probability is $P=\frac{n}{s}$, which we can use in this question. $n$ in this case would be $52$, and $s$ would be $10,000$. $P=\frac{n}{s}$ $P=\frac{52}{10000}$ $P=\frac{13}{2500}$ There is a $\frac{13}{2500}$ probability that the item picked will be defective.
