Question

bag contains 5 red balls and some blue balls. If the probability of drawing a blue ball is double that of a red ball, find the probability of drawing a blue ball. *nn​

Answer 1

Answer:

10/15=2/3

Step-by-step explanation:

If the probability of drawing a blue ball is double of the red ball,

Then, double of 5 is 10. So the bag contains 10 blue balls.

And the probability of drawing a blue ball is 10/15 or 2/3.

Answer 2

Answer:

Let Number of blue balls be n.

Now probability of getting of blue ball from bag equals to n/n+5 and probability of getting a red ball will be 5/n+5.

From given condition , n/n+5=2∗5/n+5 which gives n=10
