What is the probability of getting 2 heads when 2 coins are tossed?
The probability of tossing two heads in two coins is 0.25.
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 probabality of flipping three heads when flipping three coins one after another?
The probability of flipping three heads when flipping three coins is 1 in 8, or 0.125. It does not matter if the coins are flipped sequentially or simultaneously, because they are independent events.
What is the probability that exactly two times head are being tossed?
The answer depends on how many times the coin is tossed. The probability is zero if the coin is tossed only once! Making some assumptions and rewording your question as "If I toss a fair coin twice, what is the probability it comes up heads both times" then the probability of it being heads on any given toss is 0.5, and the probability of it being heads on both tosses is 0.5 x 0.5 = 0.25. If you toss it three times and want to know what the probability of it being heads exactly twice is, then the calculation is more complicated, but it comes out to 0.375.
Five coins are tossed How many outcomes have either four heads or four tails?
1/4
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 of getting 2 heads when 2 coins are tossed?
The probability of tossing two heads in two coins is 0.25.
If a coin is tossed then what is the probability that the number is 5?
Coins do not have numbers, there is only the probability of heads or tails.
Four coins tossed what is the probability of tossing all heads?
If they are fair coins, it is 1/16.
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 probability of getting all heads if 3 coins are tossed simultaneously?
There is a probability of 0.5 of heads on each coin, so there is a 1/2 * 1/2 *1/2 = 1/8 = 0.125 chance that all coins land heads. You can also express this as a percentage, 12.5% chance. The odds are 1 in 8 that this can happen.
The probability that both of two tossed coins will come down heads is?
1 chance in 4
When tossing 5 coins simultaneously what is the probability one will land heads up?
The probability that exactly one will land heads up is 0.15625
What is the probability that exactly two coins come up heads when four coins are tossed?
6/16 = 3/8
What is the getting one tail when two coins are tossed simultaneously?
It is the event that one of the two coins lands showing tails and the other shows heads.
Three fair coins are tossed at the same time What is the probability that one of the coins will show heads and the other two will show tails?
2/9
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
