Answer 1

Total balls = 18
No of red balls = x
No of balls which are not red = 18-x


1) probability ( not red) = 18-x/ 18

probability (red) = x/18

2) total balls = 20
Red balls =x+ 2
Probability (red ball ) = 9/8 (x/18)

X+ 2/ 18 = 9/8 (X/ 18)
X+ 2 / X = 9/8
8x + 16 = 9x
16 = x
No of red balls = 16

Answer 2

Answer:

Step-by-step explanation:

Hii

Total balls = 18

No of red balls = x

No of balls which are not red = 18-x

probability ( not red) = 18-x/ 18

probability (red) = x/18

total balls = 20

Red balls =x+ 2

Probability (red ball ) = 9/8 (x/18)

X+ 2/ 18 = 9/8 (X/ 18)

X+ 2 / X = 9/8

8x + 16 = 9x

16 = x

So we conclude that -

No of red balls = 16
