If you roll two dice What is the probabiltity of rollong a seven (the number on the dice add up to 7) on or before the eighth roll?
To find the probability of rolling a seven with two dice on or before the eighth roll, we first determine the probability of rolling a seven in a single roll, which is 6/36 or 1/6, since there are six combinations that yield a sum of seven. The probability of not rolling a seven in one roll is 5/6. Therefore, the probability of not rolling a seven in eight rolls is (5/6)^8. Thus, the probability of rolling at least one seven in eight rolls is 1 - (5/6)^8, which is approximately 0.6651 or 66.51%.
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.
What is the probability of getting a diamond and a black 7?
The probability of getting a diamond and a black seven is zero. Diamonds are red.

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
