Question

a bag contains 8 green balls and some red balls if the probability of drawing a red ball is half of that of green ball find number of red balls in bag​

Answer 1

Answer:

4 is the number of red balls

Answer 2

Step-by-step explanation:

let number of red ball   = x  and total number of ball = x+8

probability of drawing red ball = possible outcomes/ total number of outcomes

                                                   = x/x+8

probability of drawing green ball = 8/x+8

according to question :

8/x+8   =  1/2   x/8+x  cross multiply we get

  x  = 16

number of red ball   =    16
