What is the probability you roll a number cube twice and get an even number but not a 2?
The probability of getting an even number on both dice is (2/6) * (2/6) = (4/36) = 1/9.
The probability when rolling two dice of getting one even number but not a "2" is 10/36, which is 5/18.
Because 3/6 of the sides on a number cube have even numbers, the probability of rolling even on one number cube is 1/2(equivalent of 3/6). But since you're rolling twice, you multiply the probability of one by itself (therefore rolling 2 number cubes). So: 1/2x1/2=1/4 The probability of rolling an even number when a number cube is rolled twice is 1/4, 25%, or 1 out of 4.
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 an even number or a prime number on a cube.write as a fraction in simplest form?
What is the question of the problem if rolling a number cube labeled from 1 to 6 and the probability is one half?
There could be many questions: What is the probability of rolling an even number. What is the probability of rolling an odd number. What is the probability of rolling a number less than 4. What is the probability of rolling a number more than 3. What is the probability of rolling 1,4, or 6. Basically it could be any question about the probability of rolling half of the faces.
Gary rolls a cube numbered from 1 to 6 What is the probability that he will not roll an even number greater than 3?
What is the probability a number cube with numbers from 1-6 is tossed and an even number greater than 4 lands face up?
If the spinner is spun twice what is the probability that the arrow will stop on an even number both times?
Possible outcomes of one roll = 6. Probability of an even number on one roll = 3/6 = 0.5 . Probability of an even number on the second roll = 0.5 . Probability of an even number on the third roll = 0.5 . Probability of an even number on all three rolls = (0.5 x 0.5 x 0.5) = 0.125 = 1/8 The probability of at least one odd number is the probability of…
One out of 6 - yes but - only in the long run - if the number cube is perfectly even (i.e. not weighted) and - thrown onto an unconstrained surface without bias or spin. For example, you could improve your chances of throwing a 5 if you were able to roll the cube on its 5,1,2,6 surfaces - difficult but it would change the chances to a max of 1:4. It might even be…
A number cube has 6 sides the sides are numberd 1 to 6if the cube is thrown oncewhat is the probability of rolling a odd number?
What is the probability of rolling a 2 on a die and then re-rolling the die and getting an even number?
The experimental probability of anything cannot be answered without doing it, because that is what experimental probability is - the probability that results from conducting an experiment, a posteri. This is different than theoretical probability, which can be computed a priori. For instance, the theoretical probability of rolling an even number is 3 in 6, or 1 in 2, or 0.5, but the experimental probability changes every time you run the experiment.
