Answer:
1.56%
Step-by-step explanation:
A standard deck of cards has 52 cards, and 13 of these are hearts, as there are 4 suits, and 52/4=13. This means the probability of choosing a heart card from a deck of cards is 1/4, or 25%. Now to find the probability of doing this from 3 decks in a row, we simply cube 1/4 to get 1/64, and in percentage this is ~1.56%.
Subtract 3/4x from both sides
1/3x-4-3/4x= 3/4x+1-3/4x
-5/12x-4=1
Add 4 to both sides
-5/12x-4+4=1+4
-5/12x=5
Multiply both sides by 12/(-5)
(12/-5)*(-5/12x)= (12/-5)*(5)
x= 12
I hope that's help.
