Correct Answer: 3/5

Step 1: Count the number of white balls in the box. There are 4 white balls.
Step 2: Count the number of black balls in the box. There are 6 black balls.
Step 3: Add the number of white balls and black balls together to find the total number of balls. 4 + 6 = 10.
Step 4: Identify how many of the balls are black. There are 6 black balls.
Step 5: To find the probability of drawing a black ball, divide the number of black balls by the total number of balls. This is 6 (black balls) divided by 10 (total balls).
Step 6: Simplify the fraction 6/10. This can be simplified to 3/5.
