What is the probability of rolling an even with one roll of a numbers cube.
It is 1/4.
If the numbers are 1 to 6, there are three prime numbers in that range, a probability of 50%.
There are 6 possible numbers that can be rolled. "4" is one of those possible numbers. Probability is therefore 1/6.
About 98 percent.
Assuming the numbers are 1-6, the probability is 0.
To answer this problem you first see how many even and odd numbers there are. There are 3 odd and 3 even. so the fraction for even and odd is 3/6 so then in simplified form it is 1/2. If they ask to express the probability as a decimal number it would be .5 or.50
The probability of rolling two prime numbers on a standard pair of dice is 1 in 4, or 0.25. Take the probability of rolling a prime on one die, 3 in 6, or 1 in 2, or 0.5, and square it.
The probability is 5/16 = 0.3125
The probability of rolling two even numbers on two standard dice is 0.52, or 0.25.
The probability is 5/6.
It is 1/4.
If the numbers are 1 to 6, there are three prime numbers in that range, a probability of 50%.
There are 6 possible numbers that can be rolled. "4" is one of those possible numbers. Probability is therefore 1/6.
About 98 percent.
The factors of 10 are the numbers that divide 10 evenly: 1, 2, 5 and 10. To answer your question, you have to figure out what the probability of rolling one of these numbers is on a number cube.
Assuming the numbers are 1-6, the probability is 0.
For 6 sided dice, there is only 1 way to get a 2: (1,1). There are 36 outcomes rolling 2 dice; so the probability of rolling two numbers whose sum is 2 is 1/36.
