2 out of 3
The answer depends on what you are rolling: a number cube or some other shape? For a die, the answer is 2/3.
There is a 4 in 6 (or 2 in 3) probability of rolling a number less than a five on a standard number cube.
It is 1.
The probability of getting tails on a coin is SMALLER than rolling a number greater than 2
The probability would be 5/6 for rolling a number other than a 3.
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.
The probability of rolling a number greater than 6 on a die is 0.
2 out of 3
The probability of rolling a number less than 1 on a standard 6-sided die is zero. It will not happen.
The answer depends on what you are rolling: a number cube or some other shape? For a die, the answer is 2/3.
It is: 1 in 3
There is a 4 in 6 (or 2 in 3) probability of rolling a number less than a five on a standard number cube.
The probability is 57/216 = 19/108

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.
