Three colors

Find the probability that 3 balls of the same color will be drawn from fate with 10 white, 10 red, and 10 blue balls.

Correct answer:

p =  8.867 %

Step-by-step explanation:

C3(30)=(303)=30!3!(303)!=302928321=4060 n=10+10+10=30  p1=nn 9n1 8n2=3030 9301 8302=182030.0887  p=100 p1=100 0.0887=18002038.867%   Verifying Solution:  C3(10)=(103)=10!3!(103)!=1098321=120  p2=3 (103)/(n3)=3 120/4060=182030.0887 p2=p1
