But any time you want to calculate probabilities with two die throws, you need to use the 36 distinct outcomes.
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.
There are 36 possible outcomes.
If a spinner has six possible outcomes, then there are 36 (62) permutations of outcomes from spinning it twice.
There are four outcomes possible. Both even, both odd, and one of each twice. So, in one roll, it looks like your chances are 1 in 4. Is that what you are after?
When a number cube is rolled twice, there are 36 possible outcomes. (1,1),(1,2),....(6,6). (3,3) occurs only once. Therefore, the probability of rolling a 3 both times is 1/36.
(1/6 * 1/6) * 100 = 2.8%
Well what does the spinner look like
The possible outcomes for rolling a number cube twice are: 1,1 1,2 1,3 1,4 1,5 1,6 2,1 2,2 2,3 2,4 2,5 2,6 3,1 3,2 3,3 3,4 3,5 3,6 4,1 4,2 4,3 4,4 4,5 4,6 5,1 5,2 5,3 5,4 5,5 5,6 6,1 6,2 6,3 6,4 6,5 6,6 This is a total of 36 different combinations.
(1/6)2 = 1/36
6 possible numbers to land on the first time, 6 possible numbers to land on the second time, 6x6=36
50 times or above
Since there is a one in six chance of rolling a four on any given roll the probability is 1/6 or 0.16666... or 16.7%. Since each roll is independent the probabilities can be multiplied. For example to roll a four twice in a row is 1/6 x 1/6 or (1/6)^2. Note how quickly the probability drops. So, for a six sided dice the formula for rolling any number N times in row is (1/6)^N.
