The odds of rolling one five from two dice rolls is 136. The odds of rolling an odd number from the sum of two rolls requires that we roll one even number from one die and an odd number from another die. The odds of this happening are 12.
What is the probability of getting an odd number when rolling a dice?
The probability when rolling a regular six-sided dice that the score is an odd number is three-sixths or three out of six.
What is the probability of rolling a 3 or an odd number?
In this situation, rolling a six-sided has 6 outcomes, each of which is equally likely, so we can define the probability of an event (such as rolling a 3 or rolling an odd number) as the ratio of favorable outcomes to possible outcomes: the probability of rolling a 3 is 16 and the probability of rolling an odd number …
What is the probability of rolling a 4 or an odd number?
4 is one of the six possibilities, so the probablilty of rolling a 4 is 1/6. There are 3 even numbers up to and including six, as such the probablilty of rolling an even number is 3/6 or 1/2.
What is the probability of rolling an even number from 1 to 20?
Step-by-step explanation: From 1 to 20 (inclusive) there are 10 even numbers, so the probability of picking an even number is 10/20, or 1/2.
What is the probability of getting 1 and 5 If a dice is thrown once?
So they are mutually exclusive events, therefore their probabilities add to 1. By symmetry we expect that each face is equally likely to appear and so each has probability = 1/6. The outcome of a 5 is one of those events and so has probability = 1/6 of appearing.
What is the probability of rolling a 7?

What is the probability of rolling a 5 or an even number?
The chance of getting a 5 is 1/n. The probability of getting not an even number is (number of odd numbers on the die)/n. The probability of getting less than 8 is (number of numbers less than 8)/n.
