Probability - coloured balls

The cube has 6 blue, 8 red, and 10 green balls. The player randomly draws 3 balls. Determine the probability that he draws balls of the same color.

Final Answer:

p =  0.0968

Step-by-step explanation:

C3(6)=(36)=3!(63)!6!=321654=20 C3(8)=(38)=3!(83)!8!=321876=56 C3(10)=(310)=3!(103)!10!=3211098=120 C3(24)=(324)=3!(243)!24!=321242322=2024 a=6 b=8 c=10 d=a+b+c=6+8+10=24  n1=(3a)=20 n2=(3b)=56 n3=(3c)=120 n4=(3d)=2024  p=n4n1+n2+n3=202420+56+120=0.0968
