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
If n coins are tossed simultaneously what is the probability that they are all show heads?
(0.5)n
What is the probability of flipping 4 coins and getting all heads or all tails?
The probability of getting all heads is 1/24 = 1/16 The probability of getting all tails is also 1/24 = 1/16 The probability of all heads or all tails is the sum of the two = 1/8
A coin tossed 5 independent times.what is the probability of getting atleast 4 heads?
Prob(at least 4 heads) = Prob(4 heads) + Prob(5 heads) = 5/32 + 1/32 = 6/32 = 3/16
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.
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
If n coins are tossed simultaneously what is the probability that they are all show heads?
(0.5)n
The probability that both of two tossed coins will come down heads is?
1 chance in 4
What is the probability that exactly two coins come up heads when four coins are tossed?
6/16 = 3/8
A coin tossed six times what is the probability of getting two heads?
1/36
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 of seven coins tossed simultaneously and all of them landing on heads?
It is 1/2^7 = 1/128.
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.
A coin is tossed 60 times It landed on heads 21 times what is the experimental probability of getting heads?
1/2
A coin is tossed four times What is the probability of getting 4 heads in a row?
It is 1/16.
