(1 point) Xenia writes a short program that randomly generates a 6-bit string (that is, a bit string of length 6) whenever the user clicks the button. a. Consider the event that a single 6-bit string is generated. What is the cardinality of the sample space of possible outcomes? |S|= b. What is the event E that it generates 101010? E={ } c. What is the event that it generates an 6-bit string that ends with 101? E={ d. What is the event that it generates an 6-bit string that has weight 5? E={ }
