Answer:
5/7

probability = expected outcome/sample space
sample space = total number of balls = 20 + 8

expected outcome = no. of black balls = 20
probability = 20/28 = 5/7

Step-by-step explanation:
no. of white balls=8
no. of black balls=20
total outcomes=20+8=28
probability of getting black ball=no. of possible outcomes/no. of total outcomes
P(b)=20/28=5/7
