Possible outcomes of rolling a die 5 times = 6^5
Number of outcomes including rolling exactly one 4: 5^5 (5*5^4)
5^5/6^5 = 3125/7776 ~= 0.4019

A number cube is rolled 2 times in a row What is the probability of rolling a 3 both times?
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.
If a die is rolled 6 times what is the probability of 3 appearing exactly 2 times?
1/12 possibilty.
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)
A fair dice has 4 faces numbered 1 to 4 What is the probability of rolling a 2 exactly 3 times in 10 rolls of the die?
The probability is 0.2503
When rolling one die 12 times what is the probability of rolling a 2?
The probability of rolling at least one 2 when rolling a die 12 times is about 0.8878. Simply raise the probability of not rolling a 2 (5 in 6, or about 0.8333) to the 12th power, getting about 0.1122, and subtract from 1.
If a hexahedral die is rolled two times what is the probability of not rolling a five both times?
25/36
Die is rolled 9 times probability of rolling no more than 2 threes?
It is 0.8217
If a dice is rolled three times what is the probability of rolling a 3 each time?
50% chance
A die is rolled 10 times what the probbility all are 6?
The probability of rolling a 6 is 1/6. The probability of rolling 10 times a 6 is (1/6)10 or 1.654X10-8.
Suppose a die is rolled 400 times and the number of times a 5 is rolled is 60 Calculate the empirical probability of rolling a 5 based on this data?

A die is rolled 5 times what is the probability of rolling exactly one 2?
Possible outcomes of rolling a die 5 times = 6^5 Number of outcomes including rolling exactly one 2: 5^5 (5*5^4) 5^5/6^5 = 3125/7776 ~= 0.4019
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 die is rolled 375 times and 5 occurs 80 times what is the probability of rolling a 5?
The probability of rolling a 5, based on the information given, is 80/375 or 16/75. Your problem describes a relative frequency approximation of probability.
A fair die is rolled 180 times what is the probability of rolling a six?
The probability of rolling a six is 1 out of 6, or 1/6. Now, perhaps your question is: If I roll a die 180 times, what is the probability of rolling a six at least once. This is the same as rolling a die 180 times and never once rolling a six. The probability is (5/6)180 which is 5.59 x 10-15.
What is the probability of rolling exactly 2 twos when rolling a die 4 times?
It is 0.375 = 3/8
A number cube is rolled 2 times in a row What is the probability of rolling a 3 both times?
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.
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.
