Question:-

There are 2 red, 3 blue and 5 black balls in a bag. A ball is drawn from the bag without looking in to the bag. What is the probability of getting a red ball?

Solution:-

$total \: number \: if \: balls = 2 + 3 + 5 \\ = 10$

$probability = \frac{red \: balls}{total \: balls} \\ = \frac{2}{10} \\ = \frac{1}{5}$
