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 3 times what is probability of getting an even number?
if a die is rolled.What is the probibil ty that an even number divisible by 3 appears
Define the probability of something happening?
The probability that something will happen is the number of times that that something can occur divided by the number of times that anything can occur. An example would be to consider a standard deck of 52 cards. There are 4 sevens in the deck, so the probability of drawing a seven is 4 in 52, or 1 in 13, or about 0.0769.
If a die is rolled 3 times what is the probability of having a sum of 5?
3_18 3_18
If a die is rolled 6 times what is the probability of 3 appearing exactly 2 times?
1/12 possibilty.
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 of a sum of 5 on a number cube?
The answer depends on how many times it is rolled.
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?
15
Is it true that the probability of an event is the number of ways it can occur divided by the number of times it cannot occur?
No.
How do you work out the probability that a biased dice will land on a six is 0.35?
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.
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.
What is the theoretical probability of getting a 5 if a number cube is rolled 50 times?
It is approx 0.99989, that is, a near certainty.
What is the probability of a single number on a 6-sided die rolled 84 times?
-78
I rolled the dice 120 times what's the probability of getting a 6?
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.
What is the experimental probability of rolling a 2 on a number cube rolled 50 times?
Well, if you rolled a number cube 50 times and got a 2, let's do some quick math. The experimental probability would be the number of times you rolled a 2 divided by the total number of rolls, which in this case is 50. So, if you got a 2, say, 10 times, the experimental probability would be 10/50, which simplifies to 1/5 or 20%. Hope that clears things up for you!
What is the probability of rolling the same number when three number cubes are rolled?
The first roll doesn't matter for probability, it just sets the number to be rolled by the other two. So: P(rolling the same number three times) = P(rolling a particular number)2 = (1/6)2 = 1/36
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.
