Arnold is playing a game where he is trying to roll a two with a standard die. If he gets a two in any of his first 6 rolls, he wins; otherwise he loses. What is the probability that Arnold wins the game? Round your answer to the nearest tenth of a percent.

satellite73 (satellite73):

easier to compute the probability he loses, subtract that number from 1

satellite73 (satellite73):

what is the probability he rolls six times with no 2?

OpenStudy (alexa98):

5/6

satellite73 (satellite73):

on one roll, yes how about on all six rolls?

satellite73 (satellite73):

hint, multiply that answer by itself six times (aka raise to the power of 6)

OpenStudy (alexa98):

5/6 *5/6 *5/6*5/6*5/6*5/6

satellite73 (satellite73):

yes then compute \[1-\left(\frac{5}{6}\right)^6\] for your answer
