Answer 1

If there are ‘x’ black balls and ‘y’ white balls, then the total number in the jar must be x + y.
Therefore, the probability of picking a black ball is the amount of black balls there are divided by the total, which is x/(x+y)

I hope this helps!

Answer 2

Explanation:

favorable events=x

total number of events=x+y

P=(favorable events)/(total number of events)=x/(x+y)
