Answer:
Addition and Subtracttion
Step-by-step explanation:
The order of operations has to with a generally accepted order to follow when evaluating a mathematical expression.
PEDMAS or BODMAS is the order of operations to follow.
The two operations that are on the same level within the order of operations are addition and subtracttion
This means that, neither has a preference over the other.
(2)2+1=5
3(1)+1=4 is your answer
The two numbers are (5+ √(129))/2 and (5-√(129))/2.
(5+ √(129))/2+ (5-√(129))/2= 5
(5+ √(129))/2* (5-√(129))/2= -26

Answer:
4/663
Step-by-step explanation:
There are 4 queens and 4 kings in a deck. Drawing a queen would be 4/52. Drawing a king afterwards with replacing the queen would be 4/51 because you took a queen but didn't replace that one queen card so the deck has only 51 cards left after you drew the queen. Drawing a queen would not affect your chance of drawing a king card, it will only affect the total number of cards left because you didn't replace the card afterwards. 4*4=16;52*51=2652. 16/2652 can be simplified to 4/663 by dividing 4 to both numbers. 16/4=4 and 2652/4=663. The probability of drawing a queen then a king without replacement would be 4/663.
