A single dice is rolled, what is the probability of rolling a four

Answer 1

Assuming we have a normal (size-sided) die, there are 6 outcomes with an equal change of coming true. These outcomes are the values {1, 2, 3, 4, 5, 6}. Since we are looking for the an outcome of 4, which happens only once in the set, we have a probability of 1/6.
