Questions & Step-by-Step Solutions
If a bag contains 5 red balls and 3 blue balls, what is the probability of drawing a red ball?
Step 1: Count the number of red balls in the bag. There are 5 red balls.
Step 2: Count the number of blue balls in the bag. There are 3 blue balls.
Step 3: Add the number of red balls and blue balls together to find the total number of balls. 5 red + 3 blue = 8 total balls.
Step 4: To find the probability of drawing a red ball, divide the number of red balls by the total number of balls. This is 5 red balls divided by 8 total balls.
Step 5: Write the probability as a fraction: Probability of red ball = 5/8.
