Answer 2

Analysis and Solution

To determine the number of tourists who knew both English and French, we can use a Venn diagram or a set intersection approach. Let's break down the information given:

- Total number of tourists: 100 - Number of tourists who didn't know English or French: 12 - Number of tourists who knew English: 73 - Number of tourists who knew French: 80

To find the number of tourists who knew both English and French, we need to subtract the number of tourists who didn't know either language from the total number of tourists. Let's calculate it step by step:

1. Start with the total number of tourists: 100. 2. Subtract the number of tourists who didn't know either language: 12. 3. Subtract the number of tourists who knew English: 73. 4. Subtract the number of tourists who knew French: 80.

Let's calculate it:

100 - 12 - 73 - 80 = -65
