In a bag of 10 balls, 4 are red and 6 are blue. What is the probability of picking a red ball?

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.

Probability – The likelihood of an event occurring, calculated as the ratio of favorable outcomes to the total number of possible outcomes.
