Step-by-step explanation:
When we select r things from n things , we use combinations and the number of ways to select r things = 
Given : The total number of playing cards in a deck = 52
The number of different five-card hands possible from a deck = 2,598,960
In a deck , there are 26 black cards and 26 red cards.
The number of ways to select 5 cards from 26 cards = 

Hence, the number of different five-card hands possible from a deck of 52 playing cards such that all are black cards = 65,780

Answer:
B
Step-by-step explanation:
We'll use Natasha's location as 0 on a number line. To the left of her, 51/20 would be negative and 25/4 would be positive.
To find how far apart the dogs are, we would need to add the absolute value of each number:
|-51/20| + |25/4| however, this can also be rewritten as:
25/4 - (-51/20)
n^2>18
n^2 is n squared, > is the greater than symbol
