Components

In the box are 8 white, 4 blue and 2 red components.
What is the probability that we pull one white, one blue and one red component without returning?

Correct answer:

p =  0.0293

Step-by-step explanation:

$p={\displaystyle \frac{8}{8+4+2}}\cdot {\displaystyle \frac{4}{8+4+2-1}}\cdot {\displaystyle \frac{2}{8+4+2-2}}=0.0293$
