A. 1:8
Step-by-step explanation:
We have been given that several students were asked to name the kinds of animals they saw in the past week at the park.
Dogs: 8
Cat: 2
Fish: 4
Lizard: 2
We are asked to find the ratio that compares the number of cats seen to the total number of animals seen.
Let us find total number of animal by adding each type of animals as:
We can see that the students saw 2 cats, so ratio of cats to total animals would be .
Dividing 2 and 16 by 2, we will get:
Therefore, the ratio 1:8 compares the number of cats seen to the total number of animals seen and option A is the correct choice.
Method One
Your calculator might be able to do this. Mine does it like this.
6
nCr

=
15
Method 2
You could simply set up 6C2
This gives you
Method Three
You only have to do this a couple of times to see how the cancellation works.
After all the cancellation takes place you have
6*5/2 = 15
