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.

A bag contains 12 red balls and 12 blue balls. A ball is drawn at random. The probability that ball drawn is red isf
1/2P (A union qual to:?

To find the probability that a randomly drawn ball is red, we use the basic probability formula:
￼
Probability = Number of favorable outcomes/Total number of outcomes
Here:
•	The number of red balls (favorable outcomes) = 12
•	The total number of balls (red + blue) = 12 red + 12 blue = 24
So, the probability of drawing a red ball is:
￼
Probability = 12/24 = 1/2
Thus, the probability that the ball drawn is red is 1/2 or 50%.
