A fair die is rolled 4 times in succession what is the probability that even numbers are rolled all 4?

You want: P(even) * P(even) * P(even) * P(even). P(even) = 3/6 or 1/2. Therefore probability even on 4 rolls is: 1/2 * 1/2 * 1/2 * 1/2 = 1/16 = 0.0625.

A fair die is rolled 9 times compute the probability that a one appears exactly once?
The probability of a one being rolled in a fair die is 1 in 6, or 0.1666... . The probability of a one not being rolled is 5 in 6, or 0.8333... . The probability, then, of exactly one one being rolled in nine rolls is 1 in 6 times 5 in 6 to the 8th power, or about 0.0388.
If a number cube is rolled 4 times what is the probability that the same number is rolled at least twice?
It is 0.722... recurring.
What is the probability that a sum of 9 appears 13 times out of a 100 times rolled cube?
On a normal cube, the probability is 0. If there are more than 1 cubes, the answer depends on how many are being rolled for each sum.
A dice is rolled 12 times What is the probability of at least two 5's appearing?
The probability is 0.6187, approx.
What is the probability of a sum of 5 on a number cube?
The answer depends on how many times it is rolled.
A dice is rolled three times in succession what is the probability of rolling three sixes?
The probability of rolling a six is one in six. The probability of rolling three consecutive sixes is one in 216. (1/6 x 1/6 x 1/6 = 1/216)

If 3 dice were rolled 1000 times what is the probability of rolling a 14?
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.
