Q
Q: A bag contains 3 red balls and 2 blue balls. If one ball is drawn at random, what is the probability that it is red?
Solution: The total number of balls is 3 + 2 = 5. The probability of drawing a red ball is 3/5.
Steps: 5
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.
