What is the probability of rolling a seven on one roll of a die?
impossible. there are only 6 numbers on a die.
What is the probability of rolling a 4 on a die?
There are 6 possible numbers that can be rolled. "4" is one of those possible numbers. Probability is therefore 1/6.
What is the probability of rolling a four on a die?
On a standard 6 sided die the probability of rolling four is 1/6 This is because there are 6 different numbers on it, and when you roll it you read only the top number. There are 6 to choose from and all 6 are equally probable, so that probability is 1 out of 6 = 0.1666....(a recurring 6) = 16.67% to 4 significant figures
What is the probability of rolling a 2 on a die and then re-rolling the die and getting an even number?
The probability of rolling a 2 is 1 in 6. The probability of rolling an even number is 3 in 6. The probability of doing both, on two rolls, is 3 in 36, or 1 in 12.
What is the probability of rolling a four on a 6-sided die?
The probability of rolling a four on a 6-sided die is 1 in 6, or approximately 16.67%. Since the die has 6 equally likely outcomes (the numbers 1 to 6), and only one of those outcomes is a four, the probability is 1/6.
