given that,
Total no. of balls =15
let the no. of red ball = x
so, the no. of white ball = 15-x
according to ques
P(red ball) = 2× P(White ball)
=> x/15 = 2× (15-x)/ 15
=> x = 2(15- x). [ 15 to 15 cancelled]
=> x = 30 - 2x
=> 3x = 30
=> x = 10
hence, no. of red balls = 10
and no. of white balls = 15 - x= 15 - 10 = 5
