Best Answer

You find the sample space by enumerating all of the possible outcomes. The sample space for three coins is [TTT, TTH, THT, THH, HTT, HTH, HHT, HHH].

The sample space is:SM, PM, AM, CM, EM, ST, PT, AT, CT, ET, SH, PH, AH, CH, EH.

The sample space is 1R, 2R, 3R, 4R, 5R, 1W, 2W, 3W, 4W, 5W, 1B, 2B, 3B, 4B, 5B.

6/16 or 3/86/16 or 3/86/16 or 3/86/16 or 3/8

You are studying the sample because you want to find out information about the whole population. If the sample you have drawn from the population does not represent the population, you will find out about the sample but will not find out about the population.

No matter how many coins are thrown, the possibility of having AT LEAST ONE 'head' is 50%. This changes if you specify the number of 'heads' that must be shown.

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

A concept in probability theory which considers all possible outcomes of an experiment, game, and so on, as points in a space.

The sample space is 1R, 2R, 3R, 4R, 5R, 1W, 2W, 3W, 4W, 5W, 1B, 2B, 3B, 4B, 5B.

You do not need to but it can help to identify all the possible outcomes so that you don't miss any out (by mistake).

Probability not at least 1 head showing is when all 5 coins are tails: (1/2)5=1/32 Therefore probability at least 1 head is showing is 1-1/32=31/32
