# Balls

From the urn in which are 7 white balls and 17 red, gradually drag 3-times without replacement.

What is the probability that pulls balls are in order: red red red?

p =  33.6 %

### Step-by-step explanation:

$p=100\mathrm{%}\cdot \frac{17-0}{7+17-0}\cdot \frac{17-1}{7+17-1}\cdot \frac{17-2}{7+17-2}=33.6\mathrm{%}$
