Q
Q: In a box 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 = 0.4.
Steps: 5
Show Steps
Step 1: Identify the total number of balls in the box. There are 10 balls.
Step 2: Identify how many of those balls are red. There are 4 red balls.
Step 3: Use the formula for probability, which is the number of favorable outcomes (red balls) divided by the total number of outcomes (total balls).
Step 4: Plug in the numbers: Probability = Number of red balls (4) / Total balls (10).
Step 5: Calculate the probability: 4 divided by 10 equals 0.4.
