Statistics: Dice Problems
A few fun statistic problems with 6 sided dice
Problem 1: If I roll a six sided die, what’s the chances of you guessing the correct number it landed on ?
Given a six sided die the chances of you guessing 1 of those 6 different numbers {1,2,3,4,5,6} is 1 out of 6 or 1/6.
Answer: 1/6
Problem 2: If I roll a die, what’s the chances of you guessing the correct number it landed on, given that you are told it rolled on an even number?
The chances that we have given a six sided die roll of guessing the number it landed on is 1/6, the values on that die are {1,2,3,4,5,6}.
The number of even numbers {2,4,6} on the die is 3.
The number of odd numbers (1,3,5} on the die is 3.
The question is basically asking what’s the chances of guessing one of the three even numbers that the die could possibly roll on, and the answer is 1 out of 3 or 1/3.
Answer: 1/3
