What is the average number of rolls of a die to get a 6?
The probability of getting a six in a single throw is 1/6. Therefore, on average, you’ll have about six throws for every appearance of a 6. In other words, you can expect an average of 6 throws in order to see a 6 (as usual, this includes the throw that gives the 6).
On what roll would you expect to roll a 6?
The probability of rolling a 6 will always be 1/6 since the experiment is independent. So the expected number of rolls will be 1/1/6=6.
How likely are you to roll a six if you roll a dice 6 times?
Danger · hfhfhfrr . There is a 66.5% chance of it landing on a 6 at least once.
What is the expected number of rolls to get all the faces from 1 to 6?
This shows that the mean total time to get all six results is 6∑k=16k=14710=14.7.
How many times will you get a six if you throw a dice 100 times?
(a) if a fair die is rolled 100 times, how many 6’s do you expect? the probability of rolling a 6 on a fair die is 1/6, so that we expect 100 × 1/6 = 16.7 ≈ 17 6’s to be rolled.
How many dice must be rolled to have at least a 95% chance of rolling a six?
Hence, n ≥ 17 will give at least a 95% chance of rolling at least one six.
What is the expectation of getting 5 on a roll of a dice?
Two (6-sided) dice roll probability table
What is the expected number of rolls of a fair d6 6 sided dice until all 6 faces have appeared at least once?
The Expected Value
6/6 + 6/5 + 6/4 + 6/3 + 6/2 + 6/1 = 14.7 rolls. When I told my son that “you should expect to roll the die 14.7 times before all six faces appear,” he was unimpressed.
