A bag contains 10 white, 2 orange and 3 black balls. What is the probability of black balls?

3/15 Wrong

To calculate the probability of drawing a black ball, we use the probability formula:

Probability = Number of favorable outcomes/Total number of outcomes

Here:

• The number of black balls (favorable outcomes) = 3
• The total number of balls (white + orange + black) = 10 white + 2 orange + 3 black = 15

So, the probability of drawing a black ball is:

3/15=1/5

Thus, the probability of drawing a black ball is 1/5.
