It's 1/9 on the first roll and 1/9 on the second roll, so you have
a 2/9 = 22.22% chance of success on either one or the other.

What is the probability of tossing seven coins and getting 6 heads?
The probability of getting only one tails is (1/2)7. With seven permutations of which flip is the tails, this gives a probability of: P(six heads in seven flips) = 7*(1/2)7 = 7/128
What is the probability of getting exactly seven tails if you flip a coin eight times?
The probability of getting exactly seven tails if you flip a coin eight times is: P(7T1H) = 8∙(1/2)8 =0.03125 ≈ 3.1%
What is the probability of getting a 7 in a pack of cards?
It is 1: a certainty. A complete pack of cards must have a seven.
What is the probability of getting an a from Alabama?
There are four a's in ALABAMA. The probability of choosing an a from a random draw of those seven letters is 4 in 7, or about 0.5714.If you are talking about getting a grade of A from a school in Alabama, that is entirely up to you and to how well you apply yourself.

If one card is drawn from a deck of 52 cards what is the probability that it will either be a club or seven of hearts?
In a standard deck of 52 cards, there are 13 clubs and 1 seven of hearts. The probability of drawing a club or the seven of hearts, then, is 14 in 52, or 7 in 26.

What are the chances of rolling the number seven with two dice?
There are 36 permutations of two dice. Of these, six have a sum of seven. The probability, then, of rolling a seven on two dice is 6 in 36, or 1 in 6, or about 0.1667.It does not matter if two dice are rolled one time, or if one die is rolled two times. The probability of rolling a sum of 7 is still about 0.1667.The first thing to do is to identify all possible combinations which could give the sum of 7. These are: 6 and 1, 5 and 2, 4 and 3, 3 and 4, 2 and 5, and 1 and 6.Thus there are 6 possible combinations.For each of these combinations, the probability of getting the 1st number correct is 1/6 and the probability of getting the second number correct is 1/6, and so the overall probability of the combination is 1/36There are 6 ways to get 7 though so 6x 1/36 = 1/6Which means the probability that 2 dice rolls will add up to 7 is 1/6
What is the probability of getting a red king?
Assuming you're drawing from a complete shuffled 54-card deck, chances are one in twenty-seven.
A coin is flipped seven times What is the probability that the outcome is other than all seven heads?
That's the same as the total probability (1) minus the probability of seven heads. So: 1 - (1/2)7 = 127/128
