JEE Advance - Mathematics (1993 - No. 28)
An unbiased die with faces marked $$1,2,3,4,5$$ and $$6$$ is rolled four times. Out of four face values obtained, the probability that the minimum face value is not less than $$2$$ and the maximum face value is not greater than $$5,$$ is then:
$$16/81$$
$$1/81$$
$$80/81$$
$$65/81$$
