1489. Out of 5000 randomly taken parts, 32 were defective. Find the frequency of defective parts in this batch.
Solution. In this problem, we are interested in the event $A$ - the appearance of a defective part. $n=5000$ trials were conducted, and the event $A$ occurred $m=32$ times. Therefore, the sought frequency is

$$
w_{5000}(A)=\frac{32}{5000}=0.0064
$$
