Coin flips and events. 1)A coin is flipped four times. For each of the events described below, express the event as a set in roster notation. Each outcome is written as a string of length 4 from {H, T}, such as HHTH. Assuming the coin is a fair coin, give the probability of each event. (b) There are at least two consecutive flips that come up heads. (c) The first flip comes up tails and there are at least two consecutive flips that come up heads.

Write a C++ program which will perform the following operations: • Define a class with name Car and has the following members o Four private data members (Name, Model, Color and Price). . Define a constructor function (private member) which displays a text message whenever a new object is created successfully. . Define a destructor function (private member) which displays a text message whenever an object is deleted. o Define a method (public) which gets the data elements from user. . Define a method(public) which displays the data elements to user. o Create the objects of class Car and invoke its methods.
Finish the following programs. Define two public abstract class called ListNode and List. The ListNode class has 2 non-public fields, one called item which is of type Object and references the item stored in the current node, the other called myList which is of type List and references the list that contains this node. The List class has one non-public field, called size which is the number of items in the list. Both ListNode and List class are defined in the package called mylist and their subclasses in any package can access to both item, myLis or size. isEmpty() returns true if this list is empty, false otherwise. You can ignore the definition and use of the InvalidNodeException class. //definition of the ListNode class _______________________; _______________________ { _____________________; _____________________; public boolean isValidNode() {…
Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works. Next add the following public methods to the Address class and test them from main as you go: Write getters and…
c++ Implement a Class Book. Book shall have the following members: A member variable title of type std :: string.A member variable pages of the type unsigned int.A member variable current_page of type unsigned int.A parameterized constructor that takes title and pages as input parameters.A change_page function to scroll to a given page.A next_page function to scroll to the next page.A prev_page function to scroll to the previous page.A superimposed outflow operator (<<) that prints current_page.It is not allowed to scroll outside the pages of the book (0 <current_page <pages). The members must be encapsulated in accordance with the usual convention. Create goat and set functions as needed. Input follows the format: title pages start_page Output should have the following format:current_page repeated three times after calling change_page, next_page, prev_page in sequence, see comments below.

Java Programming 2/Mobile Device Programming 1) A stream is a path of communication between the source of some information and its destination. InputStream is an abstract class that defines the fundamental ways in which a destination consumer reads a stream of bytes from some source. Explain the details about the abstract Class InputStream that includes read(), skip(), available(), mark() and reset().
