What is the probability that a far six sided die rolled until the first 5 occurs on the tenth roll?

For the first 5 to appear on the tenth roll, the first nine rolls must not be a 5 and the tenth must. Therefore:
probability = (5/6)9 x 1/6
≈ 0.0323
= 3.23 %

What is the theoretical probability of rolling a 5 on a number cube if it is rolled 300 times?
The theoretical probability of rolling a 5 on a standard six sided die is one in six. It does not matter how many times you roll it, however, if you roll it 300 times, the theoretical probability is that you would roll a 5 fifty times.
What is the probability of a composite number if you rolled a six sided dice?
The probability of rolling a composite number on a 6 sided die, numbered 1, 2, 3, 4, 5, and 6, is 1 in 3. There are two composite numbers on the die, 4 and 6. The others are prime, 2, 3, and 5, or unity, 1, so there are 2 possible outcomes in an possible result set of 6, hence the probability is 2 in 6, or 1 in 3.
What is the probability of rolling a 3 or a 4 with a six sided die?
The probability of rolling a 3 or 4 with a 6 sided die is 2 over 6. Also known as one/third.
What is the probability of rolling a 3?
assuming a single six sided die the probability of rolling a three is 1/6
What is the probability of rolling a 4 on a 12 sided die?
If the faces on the 12 sided die are numbered from 1 to 12, then 1/12.
What is the probability that the number rolled will be greater that 4?
The probability that the number rolled, on a fair, six sided die, will be greater than 4 is 1/3.The probability that the number rolled, on a fair, six sided die, will be greater than 4 is 1/3.The probability that the number rolled, on a fair, six sided die, will be greater than 4 is 1/3.The probability that the number rolled, on a fair, six sided die, will be greater than 4 is 1/3.
When a six sided die is rolled then what is the probability that the number rolled will be five?
It is 1/6.
What is the probability that a far six-sided die rolled until the first 5 occurs on the tenth roll?
Assuming that the die is fair rather than far, the probability is (5/6)9(1/6) = 1,953,125/60,466,176 = 0.0323 approx.
Six-sided die is rolled What is the probability that either a 3 or 4 is rolled?
It can roll on 1,2,3,4,5,6 so the probability of 2/6 is ±33.33%
A six sided cube is rolled find the probability of P6?
A cube, by definition, must be 6 sided. The probability of getting a 6, if it is a fair die, is 1/6.
How do you calculate probability problems?
a 12-sided die is rolled. The set of equally likely outcomes is (1,2,3,4,5,6,7,8,9,10,11,12). What is the probability of rolling an 8
What is the probability that when a fair 6 sided die is rolled a prime number faces up?
On a single roll, the probability is 1/2.
Two six sided dice are rolled which number has the lowest probability of being rolled?
If two six sided fair dice are rolled, the sum of the result of both dice that has the lowest probability to come up is 2 and 12. P(2) = 1/36. P(12) = 1/36.
A six sided die is rolled once what is the probability of rolling a prime number?
1 out of 2
When you have 2 six sided dice what is the probability that the largest number rolled is a 3?
It is 1/6.
What is the probability of a six sided and four sided dice being rolled to obtain 7?
It depends on the numbers on the 4 sided die. I don't believe that is a recognised standard.
What is the theoretical probability of a six sided die when it is rolled 24 times?
well its all 50% no matter what
