The expected value if you roll a die three times is 3.5.
What is the probability that you roll a number less than five?
The answer depends on how many times a die is rolled and whether it is a fair die.For a single roll of a fair normal die, the answer is 2/3.The answer depends on how many times a die is rolled and whether it is a fair die.For a single roll of a fair normal die, the answer is 2/3.The answer depends on how many times a die is rolled and whether it is a fair die.For a single roll of a fair normal die, the answer is 2/3.The answer depends on how many times a die is rolled and whether it is a fair die.For a single roll of a fair normal die, the answer is 2/3.
You throw a die 20 times and it comes up a 5 on 17 out of 20 tosses. What is your best bet for the next roll?
Assuming a fair 6 sided die, there is a 1/6 probability for each number you could choose.
Why are the results of a punnet square probable events and not certain events?
The punnet square gives the results as probable because is it similar to rolling dice. If you have a die with four sides, when you roll it, the chance is 1 out of 4 that a certain number will show. You could roll it 20 times and it COULD show the same number 20 times. But the probability is 1 in 4 each roll. The Punnet square is the same.
How many times would you have to roll one die to roll a six five times?
If you were really unlucky, infinitely many times! The probability of that happening is very tiny but it is not zero.
