i took the test
It is used to represent one of the two possible outcomes of tossing a coin.
18 different combinations. When a coin is tossed twice there are four possible outcomes, (H,H), (H,T), (T,H) and (T,T) considering the order in which they appear (first or second). But if we are talking of combinations of the two individual events, then the order in which they come out is not considered. So for this case the number of combinations is three: (H,H), (H,T) and (T,T). For the case of tossing a die once there are six possible events. The number of different combinations when tossing a coin twice and a die once is: 3x6 = 18 different combinations.
There are 25 or 32 possible outcomes can you get by tossing 5 coins.
There are 36 possible combinations. Eleven of them have at least one four in it. That means it is 11 over 36, which is a 30.55% chance.
There are 23 = 8 possible outcomes.
There are 26 = 64 possible outcomes.
You cannot. The tree diagram for tossing 4 coins has 16 branches. So if that is done 96 times, you will have a tree with 1696 branches which is approx 4 trillion googol branches.
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
