Question

1) A bag contains 5 white balls and some blue balls. If the probability of
drawing a blue ball is double that of a white ball, determine the number of
blue balls in the bag​

Answer 1

Answer:

5 blue balls

Step-by-step explanation:

because it is having a carries 10 balls

Answer 2

Answer:

10 blue balls

Step-by-step explanation:

Let the number of blue balls be x.

P(white ball) = 5/(x+5)

P(Blue ball) = x/(x+5)

According to question,

2 × 5/(x+5) = x/(x+5)

=> x = 5×2 = 10
