A factory produces widgets in batches of 100. The probability that a widget is defective is 0.02. What is the expected number of defective widgets in each batch?
The expected number of defective widgets in each batch is 2.

Here's the reasoning:

1. We know that there are 100 widgets in each batch, and the probability of a widget being defective is 0.02.
2. To find the expected number of defective widgets in each batch, we can multiply the total number of widgets by the probability of a widget being defective: 100 * 0.02 = 2.
3. Therefore, on average, we expect 2 defective widgets in each batch of 100 widgets produced by the factory.
