Question

. An eight sided die has eight possible outcomes for each roll. (1, 2, 3, 4, 5, 6, 7, or 8). Calculate the probability of rolling a number greater than 5.

Answer 1

3/8 or 0.375

Explanation:

The probability for rolling a number greater than 5 when an eight sided die is rolled can be calculated by dividing the number of occurring in an event divided by total possible number of observation. Here, total number of possible number of observation is 8 as there are 8 possible outcome for each roll. The numbers that are greater than 5 in a 8 sided die are 6,7 and 8. Thus, total number of rolling a number greater than 5 when an eight sided die is rolled is 3.

P( rolling greater than 5)=3/8=0.375.
