Answer 1

Answer:

Step-by-step explanation:

According to question

20 - X / 20 = 2[15 - X / 15]

1 - X/20 = 2- 2X / 15

2X / 15 - X / 20 = 2-1

8X - 3X / 60 = 1

5X =60

X=12

Therefore

Blue balls = 12

And

Red balls= 3

1) P(red balls) = 3/15 = 1/5

2) P(blue balls) = 12/15 = 4/5

3) P(blue ball if 5 red ballad are added) = 12/20 = 3/5 ......
