A standard deck consists of 52 cards, distributed as follows: There are 13 cards in each of 4 suits: hearts, diamonds, spades, and clubs. Hearts and diamonds are red. Spades and clubs are black. In each suit there are 13 ranks: Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King. In Exercises 2A through 2E, assume that cards are dealt from a well-shuffled deck; that is, cards are dealt at random without replacement. PROBLEM 2A This Problem is worth 1 Point The "face" cards are those that have a person’s face on them: Jack, Queen, or King. One card is dealt. Find the chance that it is

OpenStudy (anonymous):

find the chance tha it is a face card

OpenStudy (skullpatrol):

Any ideas?

OpenStudy (anonymous):

nope

OpenStudy (skullpatrol):

Do you know what "chance" means here?

OpenStudy (anonymous):

hmmmm no idea

OpenStudy (skullpatrol):

Let's consider a simpler example, the flipping of coin. What is the "chance" it comes up heads?

OpenStudy (anonymous):

hmmm actualy i dint go through those sections so i dont hve any idea sry

OpenStudy (anonymous):

i thnk only one posiblity

OpenStudy (skullpatrol):

Either the coin can come up heads or the coin can come up tails. One possible outcome is heads and one possible outcome is tails. What is the total number of outcomes = the number of possibilities ?

OpenStudy (anonymous):

2

OpenStudy (skullpatrol):

Correct :)

OpenStudy (skullpatrol):

The number 2 now becomes your denominator in your calculation $$\frac{}{2}$$

OpenStudy (anonymous):

hmmmm nw tel me wts the numerator

OpenStudy (skullpatrol):

I asked you "What is the "chance" it comes up heads?" So there is only 1 way to get a "head" and that 1 becomes the numerator.

OpenStudy (anonymous):

so nw final ans is 1/2 rite .sure?

OpenStudy (skullpatrol):

Correct :)

OpenStudy (anonymous):

but it went wrong yarr uffffffffffff.

OpenStudy (skullpatrol):

That answer was for a simple coin not your original question. Use the same method to calculate your answer

OpenStudy (anonymous):

hmmmmm once u also try fr tht question pls

OpenStudy (skullpatrol):

How many cards are there in a standard deck? This is the same type of question you answered with how many sides does a coin have?
