The expected number is 3750.
There is a 1/8 chance to land three heads.
Each coin has 2 outcomes. Either being heads or tails. Take the outcome of each coin to the root of the number of coins. (1/2)^3 = .125 = 12.5% or a 1 in 8 chance. Take .125 and times it by 100 to get the probability out off 100 times. .125 x 100 = .125 which = 12.5%= 1 in 8 chance
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
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.
If we toss three coins 240 times, how many times can we expect the coins to have three tails showing?
3
The expected number is 3750.
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.
12.5%
There is a 1/8 chance to land three heads.
three heads two head, one tails one heads, two tails three tails
Possibilities: HHH, HHT, HTH, THH, HTT, THT, TTH, TTT. There are 3 chances out of 8 that there will be two heads and one more that there will be AT LEAST two 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)
