How do you find the probability of rolling 3 dice?
Probability for rolling three dice with the six sided dots such as 1, 2, 3, 4, 5 and 6 dots in each (three) dies. When three dice are thrown simultaneously/randomly, thus number of event can be 63 = (6 × 6 × 6) = 216 because each die has 1 to 6 number on its faces.
What is the probability of rolling a 4 or an odd number?
There are two cases, one where you first get the four, or you get an odd then a four. The probability of just rolling a 4 first is 16. If you roll one odd number before the 4, that has a chance of 12∗16 Now, you can roll 2 or 6 infinitely many times and it won’t matter.
