An urn contains 1 red ball and 10 blue balls. Other than their color, the balls are indistiguishable, so if one is to draw a ball from the urn without peeking – all the balls will be equally likely to be selected.

If we draw 5 balls from the urn at once and without peeking, what is the probability that this collection of 5 balls contains the red ball?
