Question

A jar contains green and blue Balls . If a ball is drawn at random from the jar, the probability of getting a green ball is 2/3. What is the number of green ball if there are 12 blue Balls in the jar ?​

Answer 1

Answer:

24

Step-by-step explanation:

Probability= No. of favourable outcomes/ No. of possible outcomes

Here, Probability= No. of green balls/ Total no. of balls

=> 2/3 = x/ (12+ x) { Let the number of green balls be x}

=> 3x= 24+2x. { After cross- multiplication}

=> x= 24.

Therefore, number of green balls in thr jar is 24.
