Based on the statements provided, Barry will a have a Labrador, a Collie and a Staffie at home if he has at least one dog breed.
<h3>What is logical reasoning ?</h3>
Logical reasoning in mathematics is the process of using rational and critical thinking abilities to arrive at a conclusion about a problem.
Since Barry have at least one dog breed, the possible breeds of dogs that Barry have can be determined as follows:
Statement 1: If I have a Labrador but not a Staffie, I also have a Collie
Statement 2: I either have both a Collie and a Staffie or neither.
Statement 3: If I have a Collie, then I also have a Labrador.
- From Statement 1, If Barry will have a Labrador and Collie if he doesn't have a Staffie.
- From Statement 2, Barry will have both a Collie and a Staffie or he wont have either.
- From Statement 3, Barry must have a Labrador if I he has a Collie.
Therefore, Barry will have a Labrador, a Collie and a Staffie at home if he has at least one dog breed.

To do this task the best way is always add both "sides" of ratio and divide whole group by this sum.
sum=4+7=11
33:11=3
Now we know how much is 1 and we can multiply by 4 and by 7 to find the answer.
3*4=12 - first group
3*7=21 - second group
Your result is ok.
