A fair six-sided die is rolled 12 times.
Find the probability that the die shows a 6 exactly 2 times.
Find the probability that the die shows a 6 more than 4 times.
Noah believes that the die is biased and that the probability of rolling a 6 is greater than 16\displaystyle \frac{1}{6}61. To test this claim, he rolls the die 30 times and obtains a 6 on 10 occasions. Stating your hypotheses clearly, test Noah's claim at the 5% significance level.
