Answer: 3/52 (~5.77%)

<h3>Explanation:</h3>

What we know:

  • There is a deck of 52 total cards
  • These are split into 4 suits
  • Each suit contains cards of 2-10, and a Jack, Queen, King, and Ace

How to solve:

  We need to find the probability of drawing one of 3 diamond face cards, which gives us all of the information we need. Using division, we can create a 'x amount of diamond face cards/y amount of total cards' probability.

<h3>Process:</h3>

Probability of a diamond  face card

<em>Where P is the probability of drawing that card, x is the number of diamond face cards, and y is the total amount of cards.</em>

Set up equation                                                     P = x/y

Substitute                                                               P = (3)/(52)

Answer: 3/52 (~5.77%)

Because there are 3 diamond face cards in the deck, the chance of drawing one is {3 cards out of 52 total}, which is 3/52.

The chance of drawing ANY face card is {(3 per suit, 4 suits=) 12 cards out of 52 total} 12/52 (~23.08%),

The chance of drawing ANY diamond card is {1 suit out of 4 suits} 1/4 (25%)

How to find the vertical asymptote of a function without a denominator?
Galina-37 [17]
Let's consider the equation; 

7x+2=y <-- no denominator present

If you look at the graph, you will also notice that there are no possible values of x that cannot be represented through this graph. There will always be a corresponding y coordinate. 

This can be applied to a wide range of equations where no denominator with an x value will have a vertical asymptote. Try to visualize a simpler situation with the same qualities if you don't know how to find the solution. 

Hope I helped :)

What goes outside during division with fractions? The numerator, or the denominator?
Ymorist [56]

Answer:

Denominator

Step-by-step explanation:

Think of it this way - numerator/denominator = nana/dog

Nana goes inside to the bathroom, but the dog goes outside to do its thing

If it was the other way around, it wouldn't be very pleasant.

LOL

Anyway, I hope this was helpful
