What is the probability of rolling 4 doubles in a row?
4 doubles in a row: 1296 to 1. 5 doubles in a row: 7776 to 1.
What is the probability of rolling a 6 6 times in a row?
Since there are six choices, then each time there is a 1/6 chance of rolling a six. The fact they are entirely independent of each other means we simply multiply each roll’s probability together: 1/6 × 1/6 × 1/6 × 1/6 = (1/6)4 = 1/1296 = 0.00077. Now let’s say you had already rolled double sixes.
What is the probability of rolling a 4 four times in a row?
Expert Answers
When rolled 4 times, each time has a probability of 1/6.
What are the odds of rolling 3 doubles in a row?
So on any turn, the probability of rolling a double is 6/36 = 1/6. Now each roll of the dice is independent. So the probability that any given turn will result in the rolling of doubles three times in a row is (1/6) x (1/6) x (1/6) = 1/216. This is approximately 0.46%.
What is the ratio of rolling a 2 to rolling a 5?
For example, there’s only one way to roll a two (snake eyes), but there’s a lot of ways to roll a seven (1+6, 2+5, 3+4).
…
