Q: In a bag of 10 balls, 4 are red and 6 are blue. What is the probability of picking a red ball?
Solution:
Probability = Number of red balls / Total balls = 4/10 = 2/5.
Steps: 6
Show Steps
Step 1: Count the total number of balls in the bag. There are 10 balls.
Step 2: Count how many of those balls are red. There are 4 red balls.
Step 3: To find the probability of picking a red ball, use the formula: Probability = Number of red balls / Total balls.
Step 4: Substitute the numbers into the formula: Probability = 4 (red balls) / 10 (total balls).
Step 5: Simplify the fraction 4/10. Both numbers can be divided by 2.
Step 6: The simplified fraction is 2/5. This is the probability of picking a red ball.
