For each of the following statistical experiments, write down a suitable sample space. (i) The number of passengers on an MRT train is counted. (ii) The height of a person is measured. (iii) 1000 persons are selected randomly and they are asked if they have any travel plans for this year. (iv) The maximum force (in N=Newton) is determined that a certain steel beam can withstand without breaking. (v) At a random time, the number of seconds past the current minute is determined (for instance, if the current time is 12:13:33, the outcome is 33). (vi) A dice is rolled 5 times.
