Please show work

Answer 1

QK = 8/52 = 2/13
Diamond/Ten = 16/52 = 8/26 = 4/13
Black card/Face card = 32/52 = 16/26 = 8/13

Answer 2

The probability of selecting Queen or a King is
4/52 + 4/52= 2/13

The probability of selecting a diamond or a ten
13/52+1/52= 14/52

The probability of selecting a black card or a face card
26/52+12/52=36/52

Answer 3

Since there are 4 Kings and 4 queens the chances are 8 in 52 or 2 in 13.

12 diamonds +4 tens = 16 chances out of 52 = 4/13.

26 black cards plus 6 face cards = 32 chances out of 52 or
8 in 13.

Answer 4

In a deck of cards there are 4 Queens, 4 kings, 4 10's, etc.
There are 26 red and 26 black cards.
There are 13 diamonds, 13 hearts, etc.
There are 12 face cards (a Jack, Queen, and King in each of the 4 suits).

Probability means the chance of getting a specific card (like a queen or 10 or a diamond or a black card) out of the 52 possibles.

So the chances of selecting a queen is 4/52, or 7.7%.
The chances of selecting a diamond is 13/52 or 25%.
The chances of selecting a black card is 26/52 or 50%.

Answer 5

There are 52 cards in the deck.
4 are queens
4 are kings

so there are 8/52 outcomes for success ~ .153

There are
13 diamonds ( of which one is a 10)
3 other tens
so there are 16/52 outcomes for success ~ 0.307

There are
26 black cards (of which 6 are black face cards)
6 other red face cards
so there are 32/52 outcomes for success ~ 0.615

Answer 6

1. 4/52 and 4/52
2.13/52 and 4/52
3.13/52 and 12/52

The total number in a deck of cards is 52.
Find the number of cards in the pack with that possibility e.g. in a pack of cards there is 4 Queens, so chance of picking a queen is 4/52. Of course you can make the fraction smaller by dividing both sides by 4 , so it would be 1/13.

You should do the same with all the fractions above find the lowest common denominator and divide above and below the lines.
