Question

A local animal shelter currently has 18 dogs and 24 cats available for adoption. Six of the dogs are male. If the species and sex of the animals are independent, how many cats are female?

A) 6
B) 8
C) 12
D) 16

Answer 1

D

Explanation:

Answer 2

Correct choice is D

Explanation:

Among 18 dogs 6 of the dogs are male, then 18-6=12 are female. Therefore,

`(12)/(18)=(2)/(3)` of the dogs are female.

If the species and sex of the animals are independent, then
`(2)/(3)` of all cats are female. A local animal shelter currently has 24 cats, then the number of cats that are female is

`(2)/(3)\cdot 24=16.`
