There are 23 or 8 possibilities; one is HHH. So, probability of HHH is 1/8 or 0.125.

What is the probability of tossing a fair coin ten times and getting ten heads in a row?

Answer this Question : Probability of getting 10 heads in a row is(1/2)^10 = 1/1024 = 0.000976 or 0.098 %



What is the probability of tossing a coin 9 times and getting at least one tail?

The probability of tossing a coin 9 times and getting at least one tail is: P(9 times, at least 1 tail) = 1 - P(9 heads) = 1 - (0.50)9 = 0.9980... ≈ 99.8%



What is the probability of tossing a coin three times and getting it on heads each time?

Each toss has a 1/2 probability of getting heads. Each toss is an independent event. So three heads in a row (heads AND heads AND heads) would have a probability of:1/2 * 1/2 * 1/2 = (1/2)^3 = 1/(2^3) = 1/8 = 12.5%


What is the probability of getting heads three times in a row when tossing a coin?

Ideally, the probability of getting any specific combination of length n is 0.5n = 1/2n. For n = 3, this is 0.125 = 1/8.



What is the probability of getting tails if a coin is tossed 4 times?

If you look at the as the probability of getting 1 or more tail in 4 coin tosses, you would then calculate the probability of tossing 4 heads in a row and subracting that from 1. The probability fo tossing 4 heads is 1/2 * 1/2 * 1/2 * 1/2 = 1/16. 1 - 1/16 = 15/16.


What is the probability of tossing a coin 5 times and getting all tails?

The probability of tossing a coin 5 times and getting all tails is:P(TTTTT) = (1/2)5 = 0.03125 ≈ 3.13%


Can someone give me one interesting fact about probability?

If you have tossed a fair, balanced coin 100 times and it has landed on HEADS 100 consecutive times, the probability of tossing HEADS on the next toss is 50%.


What is the probability of flipping a coin 3 times and getting 3 heads?

The probability of flipping a coin 3 times and getting 3 heads is 1/2


What is the probability of getting heads from a coin 9 times in a row?

If you continue tossing the coin forever, it is effectively a certainty. So probability = 1 If you toss it only 9 times, it is (1/2)9 = 1/512 = 0.00195 (approx)


What is the probability of getting 3 for tossing a die 300 times?

The probability of getting 3 is virtually 1. It is 1.76 septillionths less than 1.


When a coin is tossed three times what is the probability of getting at most two heads?

The opposite of getting at most two heads is getting three heads. The probability of getting three heads is (1/2)^2, which is 1/8. The probability of getting at most two heads is then 1 - 1/8 which is 7/8.


What is the probability is of getting 3 heads in a row if I toss the coin 10 times?

The probability of getting 3 or more heads in a row, one or more times is 520/1024 = 0.508 Of these, the probability of getting exactly 3 heads in a row, exactly once is 244/1024 = 0.238


In tossing 10 coins the probability of getting exactly 5 heads is?

252/1024 or 0.246. One method of calculating it is this: The total number of outcomes possible by tossing a coin 10 times is 2 to the 10th, which is 1024. In addition, getting 5 heads in 10 tosses is like arranging 5 identical objects in 10 spaces (the remaining 5 spaces are by default Tails), which can be done in 10C5 ways, which is 252. So the probability of getting 5 heads is 252/1024.



What is the empirical probability of tossing a coin 5 times and obtaining at least 3 consecutive heads?

The empirical probability can only be determined by carrying out the experiment a very large number of times. Otherwise it would be the theoretical probability.


A coin is tossed twice what is the probability that it will show heads both times?

The probability is 0.25.Look at it this way--if you toss a coin twice, there are four equally-probable outcomes:tails, tailstails, headsheads, tailsheads, headsSo the probability of heads twice in a row is one in four, or 25%.the chance of tossing heads is 1/2 (50%) The chance of tossing the next heads is 1/2 (50%) 1/2 x 1/2 = 1/4 (25%)


What is the probability of tossing a coin 25 times and it landing on heads twice?

75 over 2^23 (2 times itself 23 times, 2x2x2x2x2 etc...)



What is the probablity that the sequence will be heads-heads-heads if you toss a coin 3 times?

the probability of getting heads-heads-heads if you toss a coin three times is 1 out of 9.


If you toss 4 coins what is the probability of tossing all heads?

Take your base chance of getting heads, 1/2, and raise it to the power of the number of times you flip the coin, 4. (1/2)4 = 1/16 = .0625 = 6.25 %
