A bag contains 3 red balls and 2 blue balls. What is the probability of drawing a red ball?
Correct Answer: 0.6
Step 1: Count the number of red balls in the bag. There are 3 red balls.
Step 2: Count the number of blue balls in the bag. There are 2 blue balls.
Step 3: Add the number of red balls and blue balls together to find the total number of balls. 3 red + 2 blue = 5 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 3 red balls divided by 5 total balls.
Step 5: Write the probability as a fraction: 3/5.
Step 6: Convert the fraction to a decimal if needed. 3/5 = 0.6.
