Q
Q: If a box contains 3 red balls and 2 blue balls, what is the probability of randomly selecting a red ball?
Solution: Total balls = 3 + 2 = 5. Probability of selecting a red ball = Number of red balls / Total balls = 3/5.
Steps: 5
Step 1: Count the number of red balls in the box. There are 3 red balls.
Step 2: Count the number of blue balls in the box. 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 selecting a red ball, divide the number of red balls by the total number of balls. This is 3 red balls / 5 total balls.
Step 5: The probability of randomly selecting a red ball is 3/5.
