Question

a bag contains 12 balls out of which X number of balls are white if 6 more white balls are put in the bag the probability of drawing a white ball will be doubled then that when the probability of drawing a white ball at random then the value of x​

Answer 1

$\huge{Answer :-}$

i) no of balls=12

no of white balls =x

p(white ball) = no. of favourable outcomes/no of total possible outcomes

= x/12----(1)

ii) if 6 more white balls are put in the bag

no of total balls = 18

no of white balls =x+6

p(white balls)= (x+6)/18---(2)

therefore

(x+6)/18 = 2*x/12

(x+6)/18 =x/6

x+6 = 18x/6

x+6=3x

6=3x-x

6=2x

2x=6

x=6/2

x=3

Answer 2
