If you roll a six sided dice six times you will roll an even number at least once True or False and how did you get it?

You have a 3.125% chance of not rolling an even number, because each time you roll a die you have a 50% chance of not rolling an even number, but each additional time you roll a die your chances of not rolling an even number the formula changes from 3/6 to 3/12 because the possibilities double but your chances of not rolling an even remain the same so eventually we end up with 3/96 because of rolling the die 6 times.

What is the chance of rolling a 6 twice in a row on a die?

The chance of rolling a 6 twice in a row, on a six-sided die, is 1 in 36 or 2.78%. The number of possible different results for rolling a six-sided die twice is 6 squared (6 times 6), or 36, therefore the probability of getting any one of the possible results is 1 out of 36.


What is the experimental probability of rolling a 5 on a standard die if you had trials and 15 successes?

On an unweighted die, regardless of how many successes you've had, your chance of rolling a five will be one in six. The chance of you rolling a die 16 times and getting a five each time would be 1/616, or 0.00000000000035447042. The chance of rolling a die 16 times and getting the same number (regardless of what that number is) each time, would be 1/615, or 0.00000000000212682249 Regardless of how slim that chance is though, your chance on the next roll will still be 1/6. However, if this is meant as a "real world" question, then your chances of rolling the same number so many times in a row is so low that at that point, your odds would be much higher of there being something odd with the die, or with your experiment. At that point, it would be sensible to say that the odds are very good of rolling another 5, regardless of the math, as there seems to be another factor affecting your outcome.

Rolling an odd number on a die?

In a six sided die what is the possibility of rolling 2 odd numbers in a row?

There are 3 odd (1,3,5) and 3 even (2,4,6) sides on a 6-sided die. When rolling a 6-sided die, each face has an equal chance of coming up (assuming a perfect die). Because of this, the chance of rolling an odd number once is 50%. The second roll you again have a 50% chance to roll an odd number, which means that the chance to roll two in a roll is (50% * 50%) 25%. 1/2*1/2 = 1/4 = 25% In other words, the chance of rolling an odd number is 1/2 to the Nth power, where N is the number of rolls. Rolling a dice 10 times means a chance of (1/2)n10 or 1/2 *1/2 *1/2 *1/2 *1/2 *1/2 *1/2 *1/2 *1/2 *1/2 = 1/1024 = 0,097%
