Answer: The required number of ways is 14.
Step-by-step explanation: Given that Darlene is adopting a pet and she can choose from 8 kittens and 6 puppies.
We are to find the number of ways in which she can choose a pet to adopt.
We have
the total number of pets that are available to choose from is given by
[tex]n=8+6\\\\\Rightarrow n=14.[/tex]
Since Darlene is going to adopt only one pet, so we have
[tex]r=1.[/tex]
Therefore, the number of ways in which she can choose a pet to adopt is given by
[tex]^nC_r\\\\=^{14}C_1\\\\\\=\dfrac{14!}{1!(14-1)!}\\\\\\=\dfrac{14!}{1!13!}\\\\\\=\dfrac{14\times13!}{1\times13!}\\\\=14.[/tex]
Thus, the required number of ways is 14.
