If Rob flips 3 coins what is the chance that they will come up all tails?
each time he flips a coin he has a one out of two chance it will be tails. so that is 1/2 or .5 percent. you would then multiply that number by iteself twice to get .125
What are the chances of getting tails at least twice if you throw a coin four times?
.5 or 50% probability (if not counting draws)
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 probability of getting exactly 3 heads if a fair coin is tossed 8 times?
The probability to get heads once is 1/2 as the coin is fair The probability to get heads twice is 1/2x1/2 The probability to get heads three times is 1/2x1/2x1/2 The probability to get tails once is 1/2 The probability to get tails 5 times is (1/2)5 So the probability to get 3 heads when the coin is tossed 8 times is (1/2)3(1/2)5=(1/2)8 = 1/256 If you read carefully you'll understand that 3 heads and 5 tails has the same probability than any other outcome = 1/256 As the coin is fair, each side has the same probability to appear So the probability to get 3 heads and 5 tails is the same as getting for instance 8 heads or 8 tails or 1 tails and 7 heads, and so on
What is the probability of getting two tails if a coin is flipped 3 times?
Your question is slightly vague, so I will pose a more defined question: What is the probability of 3 coin tosses resulting in Tails exactly twice?The three possible (winning) outcomes are:TTHTHTHTTThe other (losing) outcomes are:HHHHHTHTHTHHTTTSo there is a 3 in 8 chance or a probability of 3/8 = 0.375
What is the probability of getting tails twice in a row?
The probability of tossing a coin twice and getting tails both times is 1 in 4, or 25%. If you have already tossed a coin and had it land on tails, the probability that it will land on tails again the next time you toss it is 50%.
What is the probability of getting exactly 2 tails of tossing a coin?
The probability of getting two tails when tossing a coin is zero, because the coin can only have one result. If, one the other hand, you toss the coin twice, then the probability of getting two tails is 0.25, i.e. the probability of one tail, 0.5, squared.
What is the probability of tossing 4 pennies and landing on heads twice and tails twice?
4C2(1/2)4 = 6/16 = 3/8
What is the probability of tossing a tail when a coin is tossed twice?
75%
What is the probability of two consecutive different coin flips?
The probability is 1/2 if the coin is flipped only twice. As the number of flips increases, the probability approaches 1.
What is the probability if you land head twice and tails once?
The probability is 3/8.
What is the probability of a coin landing on heads twice when it is flipped 3 times?
Your question is slightly vague, so I will pose a more defined question: What is the probability of 3 coin tosses resulting in heads exactly twice? This is a pretty easy question to answer. The three possible (winning) outcomes are: 1. Heads, Heads, Tails. 2. Heads, Tails, Heads. 3. Tails, Heads, Heads. If we look at the possible combination of other (losing) outcomes, we can easily determine the probability: 4. Heads, Heads, Heads. 5. Tails, Tails, Heads. 6. Tails, Heads, Tails. 7. Heads, Tails, Tails. 8. Tails, Tails, Tails. This means that to throw heads twice in 3 flips, we have a 3 in 8 chance. This is because there are 3 winning possibilities out of a total of 8 winning and losing possibilities.
What is the probability of getting two tails if a coin in tossed twice?
It is 0.25
You flip a coin twice. What is the probability you get tails both times?
fifty fifty

A coin is tossed 4 times. What is the probability of getting tails 4 times in a row?
The probability to get tails once is 1/2 (for a fair coin) The probability to get tails twice = the probability to get it once x the probability to get it a second time The probability to get tails 4 times in a row is (1/2)4=1/16 The probability to get tails n times in a row is (1/2)n=1/2n The same thing is also true for heads (same probability: 1/2 each time)
What is the probability of getting zero tails?
The probability of getting zero tails is 1/2. The probability of getting zero tails twice in a row is 1/2 x 1/2 = 1/4. The probability of getting zero tails three times in a row is 1/2 x 1/2 x 1/2 = 1/8, etc... .
