- The name of a variable in the new programming language K is a string that can contain upper case letters, lowercase letters, digits or underscores. Further, the first character in the string must be a letter, either uppercase or lower case or an underscore. If the name of a variable is determined by its eleven characters, how many different variables can be named in this programming language? ( Note: a name of a variable may contain fewer than eleven charactersarrow_forwardA student works in a bookstore where he is required to work at least four and at most five days a week, at least one of which has to be a weekend day (Saturday or Sunday). How many different weekly work schedules can this student have?arrow_forwardyou were introduced to the set operations of "union", "intersection" and "complement." Do you see a connection between these set operators and logical operators such as "AND", "OR" and "NOT"? Can you describe what this connection is? And what about electronic switching circuits? Is there a connection there as well?arrow_forward
- A number in Z+is written on the back of each of three cards. The numbers are not necessarily different but the sum of the three numbers is 14. Each card is flipped backwards so that the number cannot be seen by anyone. Carter, Mars, and Mann each select one of the cards, being careful not to let the other two see the number that is on the card. Carter says, after looking at his card, “I know that Mars and Mann have different numbers.” Mars then says, “I already knew that thet hree cards had different numbers.” At this point, Mann confidently exclaims, “I now know all thet hree numbers!” What were the numbers and who had which number?arrow_forward(DO NOT use any other symbol except numbers in the answer slot ) Trump, Kim, Justin, Modi, Putin and Sefu are at a round table dinner.[The answers of the following questions are integers.Put the answer only.Don’t use space,decimal points,comma etc] Now, It is known that if any two of Trump, Kim and Putin sit beside each other (while sitting in a linear fashion), the dinner may end up in a disaster. In how many ways can they sit so that the dinner may NOT end in a disaster (i.e. how many ways can they sit so that none of Trump, Kim or Putin sits adjacent to each other)?arrow_forwardDetermine whether there appears to be an Interaction by writing “YES” or “NO” in the appropriate provided spacearrow_forward
