What are the odds of rolling 3 of the same number?
1/36
The three dice are rolled fairly without any cheating. Each of the dice rolls is an Independent Event, that is the outcome from anyone dice roll has no impact whatsoever on the outcome of any other dice roll. The probability of all three happening is the product of the three probabilities: 1 × (1/6) × (1/6) = 1/36.
What is the probability of picking two the same numbers?
For independent events P(A ∩ B) = P(A) * P(B). Therefore the probability that they both pick the same number is 1/100 * 1/100.
What are the odds of guessing a 3 digit number?
If you include the one and 2 digit integers with enough zeros prepended to make them 3 digit, then your possibilities range from 000 to 999, which would give you 1,000 different 3-digit integers. With that your chances of guessing the right one would be 1/1000 or 0.001.
How do you predict 3 dice rolls?
Three dice are roll at the same time, number of attainable outcome can be 63 = (6 × 6 × 6) = 216 because each die has 1 to 6 number on its dots. i.e. (1, 1, 1), (1, 1, 2), (1, 2, 1) and (2, 1, 1). Question 4: Three dice are thrown together. Find the probability of getting a total of 6.
Frequently Asked Questions
How many combinations of 3 employees can be chosen from the set of 9?
84
So in this case, n = 9 and r = 3, so the calculation would be 9! / (3!( 9-3)!) = 84. Therefore, there are 84 unique groups of 3 that can be formed out of 9 people.
Is birthday paradox true?
The birthday paradox refers to the counterintuitive fact that only 23 people are needed for that probability to exceed 50%. The birthday paradox is a veridical paradox: it seems wrong at first glance but is, in fact, true.
What are the odds of being born on any given day?
What are the odds that this random person will have a birthday on the one day out of 366 possible days that you were born too? The odds are 1/366, or 0.0027%!
Why is the birthday paradox true?
The Probabilities of the Birthday Paradox Are Exponential
"Most importantly, people significantly underestimate how quickly the probability increases with group size. The number of possible pairings increases exponentially with group size.

- How do you find the probability of at least 2 events happening?
- Use the specific multiplication rule formula. Just multiply the probability of the first event by the second. For example, if the probability of event A is 2/9 and the probability of event B is 3/9 then the probability of both events happening at the same time is (2/9)*(3/9) = 6/81 = 2/27.
- What does at least 2 mean in probability?
- 'At least two' means two or more than two and 'at most two' means two or less than two. For example, if we are tossing 10 coins and we want to find out the probability that there are (a)at least two heads and that there are (b)at most two heads.
- What is the probability of at least one event happening?
- The probability of at least one event can be solved by finding the probability of the complement (fail) event and then multiplying it by itself the number of times determined by the number of trials, or simply raise it to a power equal to the number of trials. The result should then be subtracted from 1.
