A 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 number of blue balls in the bag.

Text Solution

AI Generated Solution

To solve the problem step by step, we will follow these instructions: ### Step 1: Define the Variables Let the number of blue balls in the bag be represented as \( x \). ### Step 2: Identify the Total Number of Balls The total number of balls in the bag is the sum of the red balls and the blue balls. Since there are 5 red balls, the total can be expressed as: \[ ...
