What is the probability of rolling an even number on a number cube?
1/2
What is the probability of rolling a 4 on a number cube?
1/2
What is the probability of rolling a number less than five on a standard number cube?
There is a 4 in 6 (or 2 in 3) probability of rolling a number less than a five on a standard number cube.
What is probability of rolling 3 on fair number cube?
2/36
The probability of rolling an even number when number cube is rolled twice?
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.
What is the probability of rolling a number other than a 1 or 2 on a number cube?
2 out of 3
What is the probability of rolling the even number on a six sided number cube?
1/2!
What is the probability of not rolling an even number on a number cube?
3/6 or 1/2
What is the probability of rolling a composite number with one roll of a number cube?
The composite numbers on an ordinary cube are 4 and 6 so the probability of rolling a composite is 2/6 = 1/3
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 a 2 or not rolling a 2 using a regular 6-sided number cube?
1 in 6 = rolling a 2 5 in 6 = not rolling a 2
What is probability of rolling a number less than or equal to 2 on then number cube?
It is 1/3
