Answer 1

Answer:

4

Step-by-step explanation:

let the no. of green balls be x

probability (getting green ball)=x/12

which is equal to 2/3( given)

x/12=2/3

x=8

no. of red balls =12-8=4 ans.....

Answer 2

Answer:

4

Step-by-step explanation:

let no. of green marbles be= x

$x=12*\frac{2}{3}$

no. of green marbles=8

no. of red marbles= total marbles-green marbles

                              = 12-8

no. of red marbles= 4
