a bag contain 14 balls of which x or white if 6 more white balls r added 2 dat bag da probability of drawing white ball is 1/2.Find da value of x??
The total number of white balls after adding 6 white balls = x+6
The total number of balls after adding 6 white balls = 14+6=20
Probabillity of getting white ball after adding 6 white balls = x+6 /20
By data
x+6/20 = 1/2
2x + 12 = 20
2x = 8
x =4
