Question

A die is rolled n times. what is the probability that at least 1 of the 6 values never apears?

Answer 1

Zero

Explanation:

The possible outcomes from rolling a die are 1,2,3,4,5 and 6. The probability of getting one of these numbers when the die is rolled

=1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6

=1

The probability of not getting one of the number plus the probability of getting one of them = 1

Therefore;

probability of not getting one of the number + 1 = 1

probability of not getting one of the number = 0
