Question: A box contains 3 red balls and 2 blue balls. If one ball is drawn at random, what is the probability that it is red?

Options:

Correct Answer: 3/5

Solution:

The total number of balls is 3 + 2 = 5. The number of red balls is 3. Therefore, the probability of drawing a red ball is 3/5.

A box contains 3 red balls and 2 blue balls. If one ball is drawn at random, what is the probability that it is red?

Step 1: Count the total number of balls in the box. There are 3 red balls and 2 blue balls.
Step 2: Add the number of red balls and blue balls together: 3 (red) + 2 (blue) = 5 (total balls).
Step 3: Identify how many of the balls are red. There are 3 red balls.
Step 4: To find the probability of drawing a red ball, use the formula: Probability = (Number of red balls) / (Total number of balls).
Step 5: Substitute the numbers into the formula: Probability = 3 (red balls) / 5 (total balls).
Step 6: The probability of drawing a red ball is 3/5.
