If two dice are rolled what is the probability of getting a number less than or equal to 6?

Assuming the dice are cubes with numbers 1-6 on their faces, the probability that a number less than or equal to 6 is shown is 1 as each die can only show numbers less than or equal to 6.
However, if you mean the SUM of the two dice is less than or equal to 6, then:
There are 36 ways in which the two dice can fall.
The sum of the two top faces can be 2, 3, 4, 5, 6; these are achieved in
2: 1+1 → 1 way
3: 1+2; 2+1 → 2 ways
4: 1+3, 2+2, 3+1 → 3 ways
5: 1+4, 2+3, 3+2, 4+1 → 4 ways
6: 1+5, 2+4, 3+3, 4+2, 5+1 → 5 ways
→ there are 1 + 2 + 3 + 4 + 5 = 15 different ways a sum less than or equal to 6 can be displayed (on the top faces).
Probability_of_success = number_ways_of_success/total_number_of_outcomes
→ Pr(sum ≤ 6) = 15/36 = 5/12

If a die is rolled what is the probability of getting a number less than or equal to 6?
Since all numbers on a die are 6 or below, the probability is 6/6, 1, or 100%.
If a die is rolled one time what is the probability of getting a number greater than 5?
It is: 1/6 Since a die is cubic in shape and has 6 sides, and there is an equal probability of getting any one of them facing up (assuming the die is not loaded), and there is only one number on a die greater than 5, that being 6, the probability of rolling such a number is therefore 1 in 6, or .1666...
What is the probability of throwing a dice and getting the number 1?
Depends on the dice! There are six sides on a dice. The number 1 is on on out of the six sides to the probability of getting a one is 1/6 which is equal to .16666 or 16.6%
Two dice are rolled find the probability that the sum of observed values is equal to 13?
If two dice are rolled, the probability that the sum of observed values is equal to 13 is zero. The sum of two dice can only lie between 2 and 12, inclusive.
What is the probability of getting a number greater than or equal to 2 when rolling a number cube numbered 1 to 6?
Probability is a ratio written as the number of desired outcomes divided by the number of possible outcomes. On a six-sided number cube, there are 5 chances of getting a number greater than or equal to 2 (2,3,4,5,6) and 6 possible outcomes (1,2,3,4,5,6) so your probability would be 5/6.

If two fair dice are rolled what is the probability that the total number of spots shown is equal to 15?
If two fair dice were rolled, there would be 36 outcomes. (1,1),(1,2),....,(6,6) The maximum sum would be 12. Therefore, the probability that the total number of spots shown is equal to 15 is zero.

What is the probability of getting heads when flipping a coin and getting a number greater than or equal to 4 when rolling a die?
It is 0.25

What is a biased coin in probability?
Probability of getting a head or tail is not equal
What is the probability of getting a 5 on a single roll?
For a 6 sided die, each number 1 - 6 has equal probability. So, probability of rolling a 5 is 1/6.
What is the probability that certain genotypes and phenotypes will occur?
This depends entirely on the genotype of the parents. The probability of getting a specific genotype is the probability of getting the correct allele from mother (1/2) multiplied by the probability of getting the correct allele from father (1/2) multiplied by the number of ways this can occur. The probability of getting a phenotype, if the phenotype is dominant, is the sum of the probability of getting two dominant alleles, and the probability of getting one dominant allele. If the phenotype is recessive, the probability is equal to the probability of getting two recessive alleles.
Is it significant to get a twelve when a pair of dice is rolled with probability of less than or equal to five tenth?
The probability to get a 12, with two dice, is 1/36.
What is the probability of getting an even number on a dice?
3/6 or 50%. if simplified it would equal 1/2.
