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:

$p=100\cdot {\displaystyle \frac{30}{30}}\cdot {\displaystyle \frac{9}{29}}\cdot {\displaystyle \frac{8}{28}}={\displaystyle \frac{1800}{203}}=8.867\mathrm{\%}$
