and the question is ... ?
when rolling a number cube when rolling a number cube what is the probability of rolling an even number or a divisor of 10? rolling an even number or a divisor of 10?
1/6
2/6 it has to be simplified so it is now 1/3
The probability of rolling an even number on a die is 3 in 6 or 1 in 2. The probability of rolling a prime on a die is 3 in 6 or 1 in 2, but one of those primes is also even. Simply add the probabilities and you find that the probability of rolling an even number or a prime on a die is 5 in 6.
If I understand the question correctly, you want the probability of each cube showing an odd number. If the number cubes are fair, then the answer is 1/4.
It is 1/2*1/3 = 1/6

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%
It is: 1 in 3
The probability of rolling a seven with one roll of a standard number cube is zero.
Total numbers on a cube = 6Even numbers on a cube = 3Probability of rolling an even number on one fair cube = 3/6 = 50% .
1 out of 6
1 out of six
1/6
Rolling a dice and getting an even number is an outcome. It is the result of rolling a dice.
one fourth
The probability of rolling a 5 on a roll of a single number cube is 1/6 (0.1666) as there is only one number 5 on a total of 6 sides on the cube.
