Question

Suppose you roll a fair 10-sided die. What is the probability that the result is 3? Use a fraction or decimal for your answer (not a percent symbol).

Answer 1

For a FAIR decahedron die (10 sided), P(rolling a 3) = 1/10, PROVIDED WE ARE ASSURED THAT ONE AND ONLY ONE OF THOSE FACES HAS A 3 ON IT.
