In a group of 20 children, 8 drink tea but not coffee and 13 like tea....
Given information:
- Total number of children = 20
- Number of children who drink tea but not coffee = 8
- Number of children who like tea (includes those who drink tea but not coffee) = 13
To find:
- Number of children who drink coffee but not tea
Solution:
To find the number of children who drink coffee but not tea, we need to use the concept of set theory and Venn diagrams.
We can represent the given information in a Venn diagram as shown below:
```
Total children (20)
/ \
Drink tea (8) Don't drink tea (12)
/ \ / \
Like tea Don't like tea Like coffee Don't like coffee
(5) (3) (?) (?)
```
From the given information, we know that:
- Number of children who drink tea = 8 (includes those who like tea and those who don't like tea)
- Number of children who like tea = 13 (includes those who drink tea and those who don't drink tea)
- Number of children who drink tea but not coffee = 8
- Number of children who like tea but don't drink coffee = 5 (since 13 - 8 = 5)
Using these values, we can fill in the Venn diagram as shown below:
```
Total children (20)
/ \
Drink tea (8) Don't drink tea (12)
/ \ / \
Like tea (5) Don't like tea (3) Like coffee (2) Don't like coffee (10)
```
Now, we can see that the number of children who drink coffee but not tea is 7 (since 12 - 5 = 7).
Therefore, the correct answer is option B, 7.
- Total number of children = 20
- Number of children who drink tea but not coffee = 8
- Number of children who like tea (includes those who drink tea but not coffee) = 13
To find:
- Number of children who drink coffee but not tea
Solution:
To find the number of children who drink coffee but not tea, we need to use the concept of set theory and Venn diagrams.
We can represent the given information in a Venn diagram as shown below:
```
Total children (20)
/ \
Drink tea (8) Don't drink tea (12)
/ \ / \
Like tea Don't like tea Like coffee Don't like coffee
(5) (3) (?) (?)
```
From the given information, we know that:
- Number of children who drink tea = 8 (includes those who like tea and those who don't like tea)
- Number of children who like tea = 13 (includes those who drink tea and those who don't drink tea)
- Number of children who drink tea but not coffee = 8
- Number of children who like tea but don't drink coffee = 5 (since 13 - 8 = 5)
Using these values, we can fill in the Venn diagram as shown below:
```
Total children (20)
/ \
Drink tea (8) Don't drink tea (12)
/ \ / \
Like tea (5) Don't like tea (3) Like coffee (2) Don't like coffee (10)
```
Now, we can see that the number of children who drink coffee but not tea is 7 (since 12 - 5 = 7).
Therefore, the correct answer is option B, 7.
