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%

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

It is 1: a certainty. A complete pack of cards must have a seven.

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.

Probability of drawing a seven of spades, from a 52 card deck, is 1/52.

There are 4 sevens so probability of drawing a seven is 4/52 or 1/13 or 0.0769.

The requirement that one coin is a head is superfluous and does not matter. The simplified question is "what is the probability of obtaining exactly six heads in seven flips of a coin?"... There are 128 permutations (27) of seven coins, or seven flips of one coin. Of these, there are seven permutations where there are exactly six heads, i.e. where there is only one tail. The probability, then, of tossing six heads in seven coin tosses is 7 in 128, or 0.0546875.

It is 1: a certainty. A complete pack of cards must have a seven.

7*(1/2)7 = 7/128 = 5.47% approx.
