Answer 2

Calculation of the Probability

The given information states that the probability of a new ballpoint pen writing poorly or not writing at all is 0.02. We need to find the probability that the pen writes well.

To calculate the probability, we can subtract the probability of the pen writing poorly or not writing from 1. This is because the sum of all possible outcomes must equal 1.

Let's denote the probability of the pen writing well as P(good), and the probability of the pen writing poorly or not writing as P(bad). We can calculate P(good) as follows:

P(good) = 1 - P(bad)

Now, let's find the value of P(bad) using the given information.

From the search results, we have the following relevant information:

- Source states that the probability of the pen writing poorly or not writing is 0.02.

Using this information, we can conclude that:

P(bad) = 0.02

Now, we can calculate P(good):

P(good) = 1 - P(bad) = 1 - 0.02 = 0.98

Therefore, the probability that the chosen pen writes well is 0.98.
