A quality-control officer inspects batches of light bulbs. Historical data shows that $8\%$ of bulbs produced are defective. If a random sample of $15$ bulbs is selected, determine the probability that exactly $2$ bulbs are defective. Express your answer as a decimal, correct to $4$ decimal places.
A manufacturer produces electronic components, and historical data shows that 15% of components are defective. A quality inspector randomly selects 8 components from the production line. Let \(X\) represent the number of defective components in the sample. What is the probability that exactly 2 components are defective?
