Question

6.An urn contains 6 blue balls and x green balls. If the probability of drawing a green ball is double that of drawing a blue ball, then x = ______ (1 Point)

Answer 1

Step-by-step explanation:

given,

no of blue balls=6

no of green balls= x

total no of balls in the basket= 6+x

probability of drawing a green ball= x/6+x

probability of drawing a blue ball= 6/6+x

x/x+6= 2(6/x+6)

x is equal to 12
