Q: A box contains 5 white and 3 black balls. What is the probability of drawing a black ball?
Solution: Total balls = 5 + 3 = 8. Probability of black ball = 3/8.
Steps: 5
Step 1: Count the total number of balls in the box. There are 5 white balls and 3 black balls.
Step 2: Add the number of white balls and black balls together. So, 5 + 3 = 8 total balls.
Step 3: Identify how many of the balls are black. There are 3 black balls.
Step 4: To find the probability of drawing a black ball, divide the number of black balls by the total number of balls. So, 3 (black balls) / 8 (total balls) = 3/8.
Step 5: The probability of drawing a black ball is 3/8.
