What is the probability of rolling a 1 or a 5 on two dice?
Hence the probability that at least one shows a 1 or 5 is 1−(2/3)2=
5/9
.
What is the probability of getting 5 when a die is thrown?
Solution: Total number of outcomes when die is thrown twice = 6 × 6 = 36. The probability that 5 will not come up either time is 25/36 and the probability that 5 will come up is
11/36
.
What is the probability of rolling a 5 then a 2?
There is a 16 probability of getting a 2 on the first roll and
a 16 probability
of getting a 5 on the second roll.
What is the probability of getting 1 and 5 if a die is thrown once?
By symmetry we expect that each face is equally likely to appear and so each has probability =
1/6
. The outcome of a 5 is one of those events and so has probability = 1/6 of appearing.
When two dice are thrown simultaneously What is the probability?
We know that the total number of possible outcomes when two dice are thrown is =
6×6=36
. We know that the probability of any event is the ratio of the number of favourable outcomes and the number of possible outcomes.
What is the probability of rolling a 1 on two dice?
| Roll a…or less Probability | 1 1/6 (16.667%) | 2 2/6 (33.333%) | 3 3/6 (50.000%) | 4 4/6 (66.667%) |

What is the probability of rolling a sum of 4?
Answer: The probability of rolling two dice and getting a sum of 4 is
1/12
.
What is the probability of rolling snake eyes?
A roll of two 1s (the lowest roll possible) on a pair of six-sided dice. The probability of rolling snake eyes is
1/36
, or 2.777… %.
What is the probability of rolling a 3 then rolling a 5?
With one die the P(3) = P(5) =
1 /6
. For 2 dice there are 2 ways to roll a 3 and 4 ways to roll a 5. 7 ways to roll a 3 or 5 so P(3 or 5) = 6/36 or 1/6.
What is the probability of 2 dice?
| Total Number of combinations Probability | 2 1 2.78% | 3 2 5.56% | 4 3 8.33% | 5 4 11.11% |

What is the probability of rolling a 1 and then a 2 on a six sided dice?
Based on this, you correctly conclude that a one and a two occurs with probability 236, or
118
.
What is the probability of getting a prime number if die is thrown once?
When a dice is thrown once, the probability of getting a prime number is
1/2
.
What is the probability of getting a number 0 when a die is thrown once?
If none of the possible outcomes are favorable for a certain event (a favorable outcome is impossible), the probability is
0
. For example, the probability of rolling a 7 on one die is = 0.
When a dice is thrown what is the probability of getting one?
If a dice is thrown twice, then the probability of getting 1 in the first throw only is. P(X). P(Y) = (1⁄6). (5⁄6) =
5/36
.
How do you find the probability of a dice?
If you want to know how likely it is to get a certain total score from rolling two or more dice, it’s best to fall back on the simple rule:
Probability = Number of desired outcomes ÷ Number of possible outcomes.
