 Hi and how are you all today? The question says in each of the following exercises 1 to 7 describe sample space for the indicated experiments. Now here the experiment which is given to us is a coin is tossed and a die is rolled only in case a head is shown on the coin. So when a coin is tossed it can either show head or tail. The die is rolled only when a head is shown that means with head. There is a possibility of obtaining 1, 2, 3, 4, 5 or 6 on the die. So the required sample space will be H1, H2, H3, H4, H5, H6. And there is also a possibility that a tail can show up. So these are the required elements of this, required of this sample space. This ends my session. Hope you enjoyed and understood it too. Have a nice day.
