There are 210 = 1024 of them.
When flipping a coin, there are 2 possible outcomes. When flipping 3 coins there are 8 possible outcomes (2^3=8). As for the situation described, there is only one way for it to not be true, if all the coins land on the same side. So either all heads or all tails. This leaves 8-2=6 possible outcomes resulting in the above situation. Therefore the probability of the given situation is 6/8 or 3/4=75%
The probabilty of you flipping 3 coins and getting all heads or tails is 0.125 or 1/8.
The probability of flipping three tails with three coins is (1 in 2)3 or 1 in 8 or 0.125.
There are 25 or 32 possible outcomes can you get by tossing 5 coins.

Because the theory of coin flipping is well understood and so theoretical probabilities can be used.
Let H mean Head and T mean Tail. The outcomes from flipping a coin twice are the same as flipping two coins together. You might get H + H, or H + T, or T + H, or T + T. So there are four possible outcomes. They are each equally likely but if you ask, "What are the chances of throwing H + H" the answer is 1 out of 4 or 25% or 0.25, and the same for throwing T + T. However, if you ask the question, "What is the chance of throwing a H with a T the probability is 2 out of 4 because there are two ways of doing that. So the probability there is 2 out of 4, or 1 out of 2, or 50% or 0.5
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.
Assuming the coins are fair, two-sided coins, and landing on their sides is not an option, there are four possible outcomes if you consider coin a having a head and coin b having a tail being a different instance from coin a being a tail and coin be having a head. Here they are; Coin A | Coin B Heads | Tails Heads | Heads Tails....| Heads Tails....| Tails
The probabilty of you flipping 3 coins and getting all heads or tails is 0.125 or 1/8.
The probability of flipping three tails with three coins is (1 in 2)3 or 1 in 8 or 0.125.
There are 25 or 32 possible outcomes can you get by tossing 5 coins.
If they are fair coins, the probability is 0.25
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%.
