It's basically the binary numbers from 000 to 111 with h's and t's in place of the 1's and 0's:
ttt
tth
tht
thh
htt
hth
hht
hhh
When tossing 4 coins at once, each coin has 2 possible outcomes: heads (H) or tails (T). Therefore, the total number of possible outcomes can be calculated as (2^4), which equals 16. This means there are 16 different combinations of heads and tails when tossing 4 coins.
three heads two head, one tails one heads, two tails three tails
The sample space for tossing 2 coins is (H = Heads & T = Tails): HH, HT, TH, TT
2 out of 8
It is (1/2)3 = 1/8
The outcomes are: heads, tails, tails or tails, heads, tails or tails, tails, heads. You can see that there are 3 possible outcomes with exactly 1 head.
Zero. Since coins land on Heads or Tails and not numbers.
The probability for that is (1/2)4 = 1/16.
Tossing two coins doesn't have a probability, but the events or outcomes of tossing two coins is easy to calculate. Calling the outcomes head (H)or tails (T), the set of outcomes is: HH, HT, TH and TT as follows: 2 heads = (1/2) * (1/2) = 1/4 1 head and 1 tail, can be heads on first coin tails on second, or just the opposite, there's two possible events: (1/2)*(1/2) + (1/2)*(1/2) = 1/2 2 tails = same probability as two heads = 1/4
