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...

TTT

TTH

THT

THH

HTT

HTH

HHT

HHH

... thus, the probability of flipping a coin 3 times and getting 2 heads is 3 in 8, or 0.375.

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.


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 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.


What is the probability of rolling 3 on a dice and flipping a coin to heads?

a three on a dice is 1/6 and aheads on a coin is 50%


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)


If you flip a coin and toss a one to six What is the probability of getting three heads?

The odds of flipping a coin and having it come up heads three times in a row is (1/2)*(1/2)*(1/2)=(1/8) or 12.5% ■

What is the probability of flipping a coin three times and it landing on heads all three times?

1/8. The probability of flipping a coin three times and it landing on head is 1/2, as a coin only has two sides. You flip a coin three times, therefore the answer is (1/2)^3 = 1/8.


What is the probability of tossing a coin three times and getting it on heads each time?

Each toss has a 1/2 probability of getting heads. Each toss is an independent event. So three heads in a row (heads AND heads AND heads) would have a probability of:1/2 * 1/2 * 1/2 = (1/2)^3 = 1/(2^3) = 1/8 = 12.5%


What is the probability of flipping NO heads when you flip 3 identical coins?

The chance of not flipping a head in each instance is 1/2. You need that to happen three times. 1/2 x 1/2 x 1/2 = 1/8 So there is a 1 in 8 chance of getting no heads from 3 coin flips.

Probability to get exactly 2 heads when flipping a coin 3 times?

The probability of throwing exactly 2 heads in three flips of a coin is 3 in 8, or 0.375. There are 8 outcomes of flipping a coin 3 times, HHH, HHT, HTH, HTT, THH, THT, TTH, and TTT. Of those outcomes, 3 contain two heads, so the answer is 3 in 8.

What is the probability of getting three heads if you flip four coins?

75% is not correct. The odds of flipping 4 independent coins is the same as flipping one coin 4 times. The number of outcomes of 4 flips is 2^4 or 16. The number of ways to exactly get 3 Heads is 4 (THHH, HTHH, HHTH, HHHT) so your chance of flipping 3 heas is 4/16 or 25%. If you include the occurance that produced 4 of 4 Heads, then you get 5/16 or 31.25%.
