Answer: 65,780
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

Proportion
48/3 = 192/?
Or vice versa
Answer: 3/8
Step-by-step explanation:1/2 divided by 4/3 is equal to 1/2 x 3/4 (you cannot divide by a fraction, you must multiply by it’s reciprocal- flip it, or cross multiply. Here we are flipping it)
Now multiply across the top ( numerators)
And then across the bottom (denominators)
1x3=3
2x4=8
Answer is 3/8
now, what is the value of the derivative at any extrema on the original function? well, by definition, if the original function has an extrema anywhere, the derivative will be the derivative of a horizontal tangent line to it, and by definition it'll be 0.
