It is 0.722... recurring.
The probability is 0.6187, approx.
The answer depends on how many times it is rolled.

It is 0.1962
You roll it many times. The probability that it lands on a six is the number of times that it lands on a six divided by the number of times the die has been rolled.
The probability of getting an even number on at least one of the 3 rolls is 7/8.
The probability is 0.6187, approx.
The answer depends on how many times it is rolled.
The probability that 14 is rolled at least once is 1 - 5.5*10-32 which, for all intents and purposes, can be treated as 1.

It is 1 - 0.3120 = 0.6880, approx.
It is 0.1962
You roll it many times. The probability that it lands on a six is the number of times that it lands on a six divided by the number of times the die has been rolled.
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.
It is approx 0.99989, that is, a near certainty.

If you rolled a die 120 times, the probability of getting a 6 is one in six. It does not matter how many times you roll the die - the probability is still one in six - except that the long term mean will approach the theoretical value of 0.166... as the number of trials increases.
