Answer:

Step-by-step explanation:

Answer 2

Answer: 3

Step-by-step explanation:

• Given, Number of red balls= 15

        Probability of drawing green ball=$\frac{1}{6}$

• To find:- Number of green balls in the bag.
• Solution:-

        Let the number of green balls be x.

        We know probability=$\frac{favourable \ outcome}{total\ possible\ outcomes}$

                      ⇒ $\frac{1}{6}=\frac{x}{x+15}$

                      ⇒ x+15=6x

                      ⇒ 5x=15

                       ∴ x= 3

• so, the number of green balls are 3 in the bag.

• Hence, required answer is 3.
