There are 52 cards in a deck of cards that consists of four suits, each containing a king, a queen, and a jack. you are dealt a card from a newly shuffled deck of playing cards. which of the following describes the probability that you will be dealt a king or a queen?
a. 1/104
b. 1/52
c. 1/26
d. 2/13

Step-by-step explanation:

There are 4 kings in a 52 card deck.

There are 4 queens in a 52 card deck.

There are 8 chances out of 52 that you will get a king or a queen.

8/52 reduces to 2 / 13 when you cancel out 4 from the top and 4 from the bottom of the probability fraction.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
