a 2 out of 6 probability
3 out of 18
Pr(1 or 5) = 1/3
Probability of rolling a 3 is 2/36 & the probability of rolling a 6 is 5/36; probability of rolling a 3 or 5 is 2/36 + 5/36 = 7/36.
1/3
If it is a fair die, the probability is 5/6.
The probability of not rolling a 6 is 5/6.
There are three odd numbers in a die: 1, 3, 5. The probability of rolling an odd number in a fair die is: P(1 or 3 or 5) = 3/6 = 1/2
3 out of 18
Well, if you put them back after you take them out, then 3=1/6 7=1/6 and
It is 4/6 = 2/3
rolling a die? 5/6
Assuming it is a regular 6 sided die, it would be 4/6 or 2/3.
Pr(1 or 5) = 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.
The probability of NOT rolling a 3 with one die is 5/6 so the probability of NOT rolling a 3 with a roll of two dice is 25/36. The probability of rolling at least one 3 is 1–25/36=11/36, a bit less than 1/3.
Probability of rolling a 3 is 2/36 & the probability of rolling a 6 is 5/36; probability of rolling a 3 or 5 is 2/36 + 5/36 = 7/36.
