Ajar contains "x" black and "y" white balls. what is the probability that a random draw is black?

probability that a random draw is black = .

Step-by-step explanation:

Given: A jar contains "x" black and "y" white balls.

To find: What is the probability that a random draw is black.

Solution: We have given that black balls  = x

                                                 white balls = y

                                     total balls = x + y

probability that a random draw is black =

probability that a random draw is black = .

probability that a random draw is black = .

Therefore, probability that a random draw is black = .
