You have two options:
Tree diagram
or binomial
I choose binomial
3 chooses 2
3*2*1/(2) = 3
3 * .5^2 * .5 = .375
or 37.5%
Or if you want it in the exact order HHT
its .5^3 which is 12.5%
The probability is 0.375
When flipping two fair coins, each coin has a 50% chance of landing on heads. The probability of both coins landing on heads is calculated by multiplying the probabilities of each coin: (0.5 \times 0.5 = 0.25) or 25%. Therefore, the odds against both coins landing on heads are 3 to 1, meaning there are three outcomes (one head and one tail, or two tails) for every one outcome where both coins show heads.
When flipping two coins, each coin has two possible outcomes: heads (H) or tails (T). The total number of outcomes when flipping two coins is 2 × 2 = 4, which includes HH, HT, TH, and TT. Out of these four outcomes, only one results in both coins landing on tails (TT). Therefore, the probability of both coins landing on tails is 1 out of 4, or 25%.
If both tosses are fair, the probability of that outcome is one in four.
The answer is 1/2 , assuming the coin is fair.
It is 1/2.
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)
The probability is 0.375
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
well since the coins have two sides,there is a 50% chance of it landing on heads
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 probabilty of you flipping 3 coins and getting all heads or tails is 0.125 or 1/8.
The answer depends on how many coins are flipped, and how often.
When flipping two fair coins, each coin has a 50% chance of landing on heads. The probability of both coins landing on heads is calculated by multiplying the probabilities of each coin: (0.5 \times 0.5 = 0.25) or 25%. Therefore, the odds against both coins landing on heads are 3 to 1, meaning there are three outcomes (one head and one tail, or two tails) for every one outcome where both coins show heads.
p(heads)= 0.5 p(heads)^4= 0.0625
http://wiki.answers.com/Q/If_you_Flip_four_coins_at_once_what_is_probability_of_2_head_and_3_tail" The probability of flipping four coins and getting 2 heads and 3 tails is ZERO 2 heads and 3 tails requires flipping FIVE coins.
0.54 or 0.0625 or 1/16.
