Question

When you send mail via the post office, you have an 80% chance that it is delivered to the correct location. If 430 letters are delivered on Monday, what is a reasonable prediction for the number of letters that are delivered to the incorrect location? Also, how many letters were delivered on Tuesday?

Answer 1

To predict the number of letters delivered to the incorrect location, subtract the percentage of letters delivered correctly from 100%. There would be around 86 letters that are delivered incorrectly out of 430. The number of letters delivered on Tuesday cannot be determined without additional information.

Step-by-step explanation:

To find a reasonable prediction for the number of letters that are delivered to the incorrect location, we can subtract the percentage of letters delivered to the correct location from 100%. Since there is an 80% chance that a letter is delivered correctly, there is a 20% chance that it is delivered incorrectly. Therefore, out of the 430 letters delivered, we can predict that around 20% of them, which is 0.2 * 430 = 86 letters, will be delivered to the incorrect location.

To find the number of letters that were delivered on Tuesday, we need more information as the question only provides information for Monday. Without additional data, we cannot determine the number of letters delivered on Tuesday.
