Hi, here is the solution.

a) A coin is tossed 4 times. So the number of sample space will be 2^4 (16).

sample space: {HHHH, HHHT, HHTH, HTHH, THHH, HHTT, HTHT, HTTH, THTH, TTHH, ...

#### Solution Summary

This solution models the experiment of tossing a coin and lists the elements of the sample space and determines how many four-digit numbers can be formed if each digit is used once and if the digits can be repeated.
