30= no of green marbles

Answer 2

There are 30 green balls .

Step-by-step explanation:

Since we have given that

Number of marbles = 40

There are some red and green.

Probability of green balls = $\dfrac{3}{4}$

So, we can rewrite it as

$\dfrac{3\times 10}{4\times 10}=\dfrac{30}{40}$

Hence, there are 30 green balls .
