Toss a fair coin 10 times. If you know that at least 7 heads are tossed, what is the probability that your first toss is heads?
Knowing the results in advance, there is a 7/10 chance that the first toss is heads. In this case "seven out of ten" is quite literal. The first toss is one of the 10, and 7 of them came up heads, so 7/10 is the chance that this particular one is one of the heads.
What is the definition of experimental probability?
Experimental Probability: The number of times the outcome occurs compared to the total number of trials. example: number of favorable outcomes over total number of trials. Amelynn is flipping a coin. She finished the task one time, then did it again. Here are her results: heads: three times and tails: seven times. What is the experimental probability of the coin landing on heads? Answer: 3/10 Explanation: Amelynn flipped the coin a total of 10 times, getting heads 3 times. Therefore, the answer is: 3/10.
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 that a seven-digit phone number has one or more repeated digits?
Assuming all digits are equally likely, then it is 0.9395.However, that assumption is flawed since some numbers begin with 0. Some sequences are reserved and so on. So the distribution of numbers is NOT truly random and the above answer depends on all seven digit numbers being equally likely..
What is the probability of seven coins tossed simultaneously and all of them landing on heads?
It is 1/2^7 = 1/128.
What is the probability that at least one tail appears when tossed 6 times?
you have 63 chances out of 64. i once witnessed a coin being tossed seven times and giving up 7 consecutive heads. we never tried it an eighth time, 7 heads and you had to go to the bar.

Did JK Rowling write all the sequences?
I don't know what sequences you mean; she did write the seven Harry Potter books (and three additional books).
How many ways can a coin come up heads seven times and tails once when tossed eight times?
If you toss a coin 8 times and there are 7 heads, then there must be one tail each time. So how many ways can we get one tail? It can occur first, such as THHHHHHH or second HTHHHHHH etc. There are 8 places to put the T so there are 8 ways to have 7 heads and 1 tail.

Seven coins are tossed What is the probability of 3 heads or 2 tails?
The probability of one event or the other occurring is the probability of one plus the probability of the other. The probability of getting 3 heads is the probability of 3 heads (1/23) multiplied by the probability of 4 tails (1/24) multiplied by the number of possible ways this could happen. This is 7c3 or 35. Thus the probability of 3 heads is 0.2734375. The probability of 2 tails is the probability of 2 tails (1/22) multiplied by the probability of 5 heads (1/25) multiplied by the number of ways this could happen. That is 7c5 or 21. Thus the probability of 2 tails is 0.1640625 The probability of one or the other is the sum of their probabilities: 0.1640625 + 0.2734375 = 0.4375 Thus the probability of getting 3 heads or 2 tails is 0.4375.

What is the probability of obtaining exactly six heads in seven flips of a coin given that at least one is a head?
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.
