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, the probability of both landing on heads in a single flip is ( \frac{1}{2} \times \frac{1}{2} = \frac{1}{4} ) or 25%. If you flip the coins 20 times, the expected number of times both will land on heads is ( 20 \times \frac{1}{4} = 5 ). Thus, while the odds for any single flip remain at 25%, over 20 flips, you would expect about 5 occurrences of both coins landing on heads.

The odds of getting 3 heads in a toss of 3 coins is 1 in 8, or 0.125. Each coin is probabalistically unrelated to each other, so you simply multiply the odds for each coin. 1 in 2 times 1 in 2 times 1 in 2 is 1 in 8.
lets get some facts odds of head on 1 coin 50% or evens odds of no head 50% or evens the possible results vary from 1 coin to 2 coins. 1 coin has 2 results heads or tails 2 coins have 4 results. heads heads, tails tails, tails heads, heads tails. each outcome has a probability of 25%. for the question we remove the heads and tail probability and we have 2 outcomes with heads and one without. so 2 to 1 chance or 33.3333 recuring chance.

There is a probability of 0.5 of heads on each coin, so there is a 1/2 * 1/2 *1/2 = 1/8 = 0.125 chance that all coins land heads. You can also express this as a percentage, 12.5% chance. The odds are 1 in 8 that this can happen.
The odds are 1 in 2.
It's human nature to think so, but no. Even after getting 100 heads in a row, the odds of the next flip being heads is still 50%.
