what is the probability of drawing two yellow marbles if the first one is placed back in the bag before the second draw. give your answer as a ratio reduced to simplest terms.

1:25

Step-by-step explanation:

There are 2 out of 10 yellow marbles.

2/10 simplified is 1/5

Sorry had to edit its multiplied by each other so its actually 1:25

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12
