I only have one for 12
12, 21
24, 42
36, 63
48, 84
16/25 because there are 3 face cards which have 4 different suits and 4 different suits for the number 6
It's 0.720. you just divide 103 and 143 and get the first three numbers
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
7*x-4-(21)=0
Solve : 7x-25 = 0
Add 25 to both sides of the equation :
7x = 25
Divide both sides of the equation by 7:
x = 25/7 = 3.571
