Answer 12

red cards = diamond cards + heart cards

Answer 13

@hartnn So there are always 13 red cards,hartnn? so 13/52?

Answer 14

there are 13 heart cards and 13 diamond cards
both are considered as red
so, total # of red cards = 26
P= 26/52=....?

Answer 15

Wait 13 diamond,13 hearts so 26?

Answer 16

hope 26/52

Answer 17

Lol yes got it. @hartnn

Answer 18

so 26/52 =0.5

Answer 19

yes, 0.5 is correct :)
Face cards - Jacks, Queens, and Kings are called "face cards" because the cards have pictures of their names.
so, in 52, how many face cards will be there ?

Answer 20

note: there are total 4jacks, 4 queens and 4 kings, one of each suit.

Answer 21

12/52

Answer 22

@hartnn

Answer 23

12/52 is correct.
how are face cards 36 in number ?

Answer 24

yay so 0.230769

Answer 25

kk calculated ace too...

Answer 26

C. is simple total 13 diamonds
P=... ?

Answer 27

13/52

Answer 28

yes, correct
d) there are 4 tens one of each suit
same way, there are 4 queens , one of each suit
P=....?

Answer 29

'or' means addition

Answer 30

0.25 for diamond cards,and what does *one on each suit* means?

Answer 31

there are 4 suits in the deck
hearts
spades
diamonds
and clubs

Answer 32

look at the wiki link for details

Answer 33

so, 4 tens are
1 ten of heart
1 ten of spade
1 ten of diamond
and 1 ten of club
same for every other card!

Answer 34

can you get d) now ?

Answer 35

Okay so i have a choice i can either go for *a ten* or a *queen* I go for queen so,4/52 = 0.0769

Answer 36

'or' in probability means we add the individual probabilities
4/52 for queen + 4/52 for a ten
(4+4)/52 will be final answer for d)...just simplify

Answer 37

Oh then that concept is confusing but okay *8/52?*

Answer 38

0.15384

Answer 39

yes, 8/52 ...simplify that.
same for last part
just add total number of face cards + total # of 5's and total # of 4 of spade

Answer 40

Face cards are 12,total 5's are 4 and spade's are 4? So,12+4+4 =20/52 =0.3846153.

Answer 41

there are total 4 4's
one 4 of heart,
one 4 of diamonds
one 4 of spades
and one 4 of clubs

Answer 42

so how many # of 4 of spades ?

Answer 43

Huh? o_O 4?

Answer 44

Face cards are 12,total 5's are 4 <---correct
there is only \(\huge 1\) 4 of spade

Answer 45

*A 4 of spades?* so only 1 spade? :p

Answer 46

there are total 4 4's
one 4 of heart,
one 4 of diamonds
one 4 of spades <------here , only 1
and one 4 of clubs

in the question "4 of spade" is asked, which is unique
in all there are 13 spades

Answer 47

Don't understand :p

Answer 48

which part ?
only '4 of spade' ?
because # of faces=12 .....correct.
# of 5's =4 ....correct (one of each suit)
# of 4 of spade =.... ?

Answer 49

I don't understand # of 4 of spade

Answer 50

ok,
there are 13 cards in each suit
A,2,3,4......9,10, J, Q, K

A,2,3,4......9,10, J, Q, K of hearts
A,2,3,4......9,10, J, Q, K of diamonds
A,2,3,4......9,10, J, Q, K of spades
A,2,3,4......9,10, J, Q, K of clubs
total =52

out of this, how many '4' of spades are there ?

Answer 51

there's 1x ace of spades in a deck
1x 2 of spades
1x 3 of spades
1x 4 of spades ######## <----
1x 5 of spades... etc

Answer 53

how many of this card are there in a deck...?

Answer 54

EXACTLY that card...

Answer 55

^ only \(\huge \color {red}1\) 4 of spade, unique!

Answer 56

Okay so there are always 13 spades...? :3

Answer 57

yes, total 13 spades
but that info you don't need here

Answer 58

E) a face card,or a 5,or a 4 of spade.

a face ---->12
a 5----->4
a 4 of spade --->1

P=(12+4+1)/52

Answer 59

Okay...:) So i have a Question when there was *A face card* why we didn't use 1?

Answer 60

because there are in all 12 face cards

one Jack of heart
one Jack of diamond
one Jack of club
one Jack of spade

total 4 jacks
similarly, 4 queens and 4 kings
total face cards = 12

Answer 61

Oh...:D so aren't spades 13 in total? :P

Answer 62

yes, there are 13 spades in all
A,2,3,4......9,10, J, Q, K of spades <-----total =13
what made you ask this ?

Answer 63

WHY ARE WE USING 1 THEN!! THAT MADE ME ASK.. :3

Answer 64

1 = A

Answer 65

because the question doesn't ask of only spades
only spades = 13
its ask for a "4 of spade"
which is unique

Answer 66

Okay :P so we use *1?* so face cards is 12,5's are 4 so 12+4+1/52 =17/52 =0.32692
