Gary rolls a cube numbered from 1 to 6 What is the probability that he will not roll an even number greater than 3?

Gary's chances of rolling either a 4 or a 6 are the same for any of the other numbers on the cube. The probability is 1 out of 3.

Find the probability of rolling a 2 on a number cube and then an even number on two consecutive rolls of a number cube?
1/6,3/6 ----------------------------------------------------------------------------------------------------- The probability of rolling a 2 is: P(2) = 1/6 The probability of rolling an even number is: P(even) = 1/2 The result on the second roll is independent of the result in the first roll. The probability of rolling a 2 and then rolling an even number is: P(2,even no.) = (1/6) ∙ (1/2) = 1/12 = 0.08333... ≈ 8.33%
What is the probability of rolling the same number twice?
In 2 rolls, it's 1/6 = 162/3% if you don't care what the number is.If you name the number you want before rolling, it's 1/36 = 27/9%.
What is the probability that 6 rolls of a fair die will show four exactly 5 times?
5 out of 36
What is the probability of rolling a sum of 8 on at least one of two rolls of a pair of number cubes?
The probability of rolling a sum of 8 on one roll of a pair of dice is 5/36.The probability of not rolling a sum of 8 on one roll of a pair of dice is 31/36.The probability of rolling a sum of 8 twice on two rolls of a pair of dice is(5/36)(5/36) = (5/36)2 .The probability of rolling first a sum of 8 and then rolling a sum that is not 8 on thesecond roll is (5/36)(31/36).The probability of rolling a sum that is not 8 on the first roll and rolling a sum of 8in the second roll is (31/36)(5/36).So The probability of rolling a sum of 8 at least one of two rolls of a pair of dice is(5/36)2 + (5/36)(31/38) + (31/36)(5/36) = 0.258487654... ≈ 25.8%.
There are 10 rolls of film in a box and 3 are defective Two rolls are selected without replacement What is the probability of selecting a defective roll followed by another defective roll?
1/15 or about 0.07
Glenn rolls a 6-sided die. What is the probability that he gets a number greater than 2 or an odd number?
5-6
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
What is the probability of rollling a 5 3times ina row?
With a fair die, it is 1/216 in three rolls, but the probability increases to 1 (a certainty) as the number of rolls is increased.
What is the probability of not rolling a 6 on a number cube?
The probability of not rolling it ever is 0.For n rolls it is (5/6)n sofor 10 rolls it is 0.1615for 20 rolls it is 2.608*10-2for 100 rolls it is 1.207*10-8 and so on.
When two dice are rolled what is the probability that both will be a five?
if you multiply the number of rolls you did you will get the answer
A single die is rolled what is the probability tha the number rolled will be greater than 3?
Total different outcomes = 6Successful outcomes = 3 (rolls of 4, 5, or 6)Probability of success = 3/6 = 1/2 = 50%
What is the probability of rolling a 6 and then a 1 on consecutive rolls of a standard sided number cube?
If you keep rolling the die, then the probability of rolling a 6 and then a 1 on consecutive rolls is 1.The probability is 1/36 for the first two throws.
What is the probability of rolling a prime number and the probability of rolling a number greater than 1 on two rolls fo a die?
First you need to work out the probability of rolling a prime number. The prime numbers on a die are 2, 3 and 5. Thus the probability of rolling a prime number is 3/6 which can be simplified to 1/2. The probability of rolling a number greater than 1 is 5/6. The probability of rolling one on one dice and one on the other is therefore 1/2 x 5/6 = 5/12. There are two possible ways round these options could come though. You might get the number greater than one on the first roll, and the prime on the second. Thus we need to multiply the probability by 2, which gives us the final answer of 5/6.
If a die is rolled 3 times what is probability of getting an even number?
The probability of getting an even number on at least one of the 3 rolls is 7/8.
What is the probability of rolling a 1 and a prime number?
If the die is rolled often enough, the probability is 1. With only two rolls of a fair die, the probability is 1/6.

The number of 6s in 37 rolls of a loaded die and binomial.
What is the probability that two rolls of a number cube will have a sum of 7?
It is 6/36 = 1/6
