If you mean 'at least' 2 heads, the probability is 50%. If you mean exactly 2,
the probability is 3/8, or 37.5%.
There are 3 independent coin tosses, each of which is equally likely to come up
heads or tails. That's a total of 2 * 2 * 2 or 8 possible outcomes (HHH, HHT, HTH,
etc.). Of these, 4 include 2 or 3 heads, which is half of 8. Only 3 include exactly 2
heads, so the probability of that is 3/8.

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.
The probability of flipping a coin three times and getting two heads is?
There are 8 permutations of flipping a coin 3 times, or of flipping 3 coins one time. They are, with the permutations of two heads bolded...TTTTTHTHTTHHHTTHTHHHTHHH... thus, the probability of flipping a coin 3 times and getting 2 heads is 3 in 8, or 0.375.
What is the probability of getting exactly two heads in three coin tosses?
33%
What is the probability of getting heads more than once if you flip a coin three times?
For 3 coin flips: 87% chance of getting heads at least once 25% chance of getting heads twice 13% chance of getting heads all three times
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.
What is the probability if you flip 3 coins and get three heads?
12.5%
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 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 the probability of getting all heads on a toss of three fair coins?
1/2 * 1/2 * 1/2 = 1/8 = 12.5%
You flip 3 coins what is the probability that you get exactly 3 heads?
There is a 1/8 chance to land three heads.
What is the probability that the first two flips will both be heads and the third flip will be tails if you flip three fair coins?
To find the probability of getting heads on the first two flips and tails on the third flip when flipping three fair coins, we multiply the probabilities of each individual event. The probability of getting heads on a flip is 1/2, so for the first two flips, it is (1/2) * (1/2) = 1/4. The probability of getting tails on the third flip is also 1/2. Therefore, the overall probability is (1/4) * (1/2) = 1/8.
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.
The probability of flipping a coin three times and getting two heads is?
There are 8 permutations of flipping a coin 3 times, or of flipping 3 coins one time. They are, with the permutations of two heads bolded...TTTTTHTHTTHHHTTHTHHHTHHH... thus, the probability of flipping a coin 3 times and getting 2 heads is 3 in 8, or 0.375.
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.
What is the probability of getting three or more heads when four coins are flipped?
Number of possible outcomes with 4 coins = 2 x 2 x 2 x 2 = 16.Number of successes = 2. (Three heads or four heads)Probaility of success = 2/16 = 1/8 = 12.5 percent
What is the probability of flipping no heads when you flip three identical coins?
The probability of flipping one coin and getting tails is 1/2. In order to find the probability of multiple events occurring, you find the product of all the events. For 3 coins the probability of getting tails 3 times is 1/8 because .5 x .5 x .5 = .125 or 1/8.
3 If you flip four fair coins what are the chances exactly three land on heads?
When flipping four fair coins, the number of ways to get exactly three heads can be calculated using combinations. Specifically, there are ( \binom{4}{3} = 4 ) ways to choose which three coins will land on heads. The probability of any specific combination of three heads and one tail is ( \left(\frac{1}{2}\right)^4 = \frac{1}{16} ). Therefore, the total probability of getting exactly three heads is ( 4 \times \frac{1}{16} = \frac{4}{16} = \frac{1}{4} ) or 25%.
