The odds of not rolling a 1 or 2 with two dice is 35 in 36. The odds of doing that 25 times in a row is (35/36)25 or about 0.4945

Note: The odds of not rolling a 1 is zero, so the answer degraded to the odds of not rolling a 2.


===================================

Opinion #2:

-- There are 36 possible outcomes when 2 dice are rolled.
-- Only one of the outcomes is a 2.
-- So the probability of NOT rolling a 2 with 2 dice is 35/36 .

-- In 25 consecutive rolls, the probability of never rolling a 2 is (35/36)25 = 49.45% .

-- The 'odds' are 1,011 to 989 against it.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What are the odds of rolling a 3 4 times in a row?

The probability of rolling a 3 on a die are 1/6. Since each roll is an independent event, the probability of rolling a 3 4 times in a row is (1/6)4 or 1/1296.The odds of something happening are the chances of it happening vs. the chances of it not happening. The chance of not rolling a 3 4 times in a row is 1-(1/1296) or 1295/1296.Therefore the odds are 1:1295

The answer depends on how many times in total the dice are rolled. As the total number of rolls increases, the probability rolling a 6 and 4 three times in a row increases towards 1.


Odds of not rolling 3 doubles in a row?

1/6 x 1/6 x 1/6 = 1/216 is the odds of getting three doubles in a row so I suppose the odds of not rolling three in a row is 215/216 or 99.54% chance.


What is th probability of rolling six three times in a row with a six sided dice?

Assuming that the die is a "normal" one (it has the numbers 1 to 6 and that it is fair), then the probability of rolling six three times in a row is 1/6*1/6*1/6 = 1/216 = 0.00463 The probability of rolling six three times in a row eventually is 1 (ie a certainty).


What are the odds of rolling a four 3 times in a row using two dice?

Assuming fair dice: With 3 dice there are 6 x 6 = 36 possible permutations (the two dice can be identified and are independent of each other). Of these there are 3 ways (1+3, 2+2, 3+1) of getting four. Probability of getting a four with 2 dice on one roll = 4/36 = 1/9 As rolls are independent, the probability of getting 4 with 2 dice 3 times in a row is 1/9 x 1/9 x 1/9 = 1/729 So the odds of it are 728 to 1 against, ie 1 in 729 or about 0.14 %.
