There are three possibilities, Heads, Tails and stand on edge
If you toss eight coins, there are 256 (28) different outcomes.
There are technically 8 possible outcomes if you are talking about the side of the coin it lands on. Each coin has 2 possible outcomes (landing on heads and landing on tails). To figure out the number of outcomes for all the coins you multiply the outcomes for all of the coins together: 2 X 2 X 2= 8.
There are 12 possible outcomes.
Each coin has two possible outcomes, either Heads or Tails. Then the number of outcomes when all 4 coins are tossed is, 2 x 2 x 2 x 2 = 16.
It is used for lots of things such as finding out the total possible outcomes of tossing coins. You find the line that corresponds with how many coins you toss and add all the numbers in that line to get the number of possible outcomes also you can use it to find combinations and permutations and triangular numbers
2x2x2=8 possible outcomes. In general for n tosses there are 2^n outcomes.
Assuming order is irrelevant, 2^5, or 2*2*2*2*2 or 32 possible combos.
24 or 16
There are 4 possible outcomes. There are 2 outcomes (heads or tails) on the first toss and 2 on the second toss. The possibilities are HH, TT, HT and TH.
There are 96 possible outcomes. A dodecahedron has 12 sides, so it has 12 possible outcomes. An octohedron has 8 sides. So for each of the 12 outcomes on the dodecahedron, the octahedron has 8 possible outcomes, hence you multiply 12 x 8 = 96.
There are 6*6*2 = 72 possible outcomes.
Two times the number of outcomes of the spin - which is not specified in the question.
