The probability would be once in 128 attempts. You don't have to toss seven coins simultaneously. the 7 tosses just have to be independent of one another.

The probability that exactly one will land heads up is 0.15625


When tossing 5 coins simultaneously what is the probability that at least 1 head is showing?

Probability of no heads = (0.5)^5 = 0.03125Probability of at least one head = 1 - probability of no heads = 1 - 0.03125 = 0.96875


What is the probability of tossing a coin and getting a head?

The probability of tossing a coin and getting heads is 0.5


What is the probability of tossing a coin and getting an even number?

Zero. Since coins land on Heads or Tails and not numbers.


What is the probability of getting 6 heads in tossing 6 coins in 6 tosses?

The probability of tossing 6 heads in 6 dice is 1 in 26, or 1 in 64, or 0.015625. THe probability of doing that at least once in six trials, then, is 6 in 26, or 6 in 64, or 3 in 32, or 0.09375.


What is the probability of of tossing heads on the first 6 tosses of a fair coin?

The probability of tossing heads on all of the first six tosses of a fair coin is 0.56, or 0.015625. The probability of tossing heads on at least one of the first six tosses of a fair coin is 1 - 0.56, or 0.984375.


What is the probability that a tail will appear when tossing 2 fair coins?

75% The chance of not having a tails but a heads on both coins is (1/2)2 or 25%, so the chance of actually having a tails on either coin is 3/4, or as a percentage 75% .


What is the probability of not tossing three heads with three fair coins?

The probability of something NOT happening is the complement of the probability of something happening. Since the probability that you DO have 3 heads is 1/8 (that is, 1/2 cubed), the complement is 1 - 1/8 = 7/8.


When tossing 3 coins simultaneously find the probability that at least 1 head is showing?

No matter how many coins are thrown, the possibility of having AT LEAST ONE 'head' is 50%. This changes if you specify the number of 'heads' that must be shown.


If four coins are tossed what is the probability of tossing all heads?

The probability is 1/21/21/2*1/2=1/16, or 0.0625 or 6.25%


What is probability of at least 2 heads on tossing 3 coins?

There are 8 permutations of three coins. Of these, 3 of them have two heads, so the probability of tossing two heads on three coins is 3 in 8, or 0.375. However, you said, "at least", so that includes the case of three heads, so the probability of throwing at least two heads is 4 in 8, or 0.5. T T T T T H T H T T H H * H T T H T H * H H T * H H H *


Two coins are tossed What is the probability of both coins are heads?

The probability that both coins are heads is the probability of one coin landing heads multiplied by the probability of the second coin landing heads: (.5) * (.5) = .25 or (1/2) * (1/2) = 1/4


What is the probability of tossing at least one head with 3 coins?

3 coins can land in 8 different ways. Only one of these ways is all tails. So the probability of rolling at least one heads is 7/8 = 87.5% .


What is the probability of flipping 2 coins and having both show heads?

If both tosses are fair, the probability of that outcome is one in four.


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 landing on an even number when tossing an 8 sided die and tossing a coin and getting heads?

1/2 * 1/2 = 1/4 1/2= probability of landing an even number 1/2 = probability of landing a heads


What is the probability of flipping three coins and all of them land up on heads?

The probability of the first coin landing heads is half (or 1/2). Similarly, the probability of the second and third coins landing heads are also 1/2 in each case. Therefore, the probability of having three heads is: (1/2)(1/2)(1/2) = (1/8)



What is a probability of tossing exactly two heads?

Coin tosses are what we call Independent Events, meaning that the results of one toss have no effect on the next toss or any thereafter. Therefore the probability of each toss is 1/2. If, however, you want to know the probability of tossing two coins, and each coin landing heads-up, you simply multiply their probabilities together, resulting in 1/4.
