What is the probability of rolling a 1 or 6 on a number cube and flipping tails on a coin?
The probability of flipping tails on a perfect coin in a perfect toss is 0.5. The probability of rolling 1 on a die is 1 in 6. Likewise, the probability of rolling 6 on a die is 1 in 6. So the probability of rolling either 1 or 6 is 2 in 6 (which is 1 in 3).
What is the probability of rolling an even number or prime number on a number cube?
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.
What is the faction of rolling a prime number?
With a standard 6-sided die, the probability of rolling a prime number is 1/2
What is the probability of rolling an even prime number with one roll of a die?
Since there is only one even prime, 2, the probability of rolling a 2 with one die is 1 in 6.
What is the probability of rolling a prime number with one roll of a number cube?
1/6
