Viefleur [7K]

Answer:

In Java:

import java.util.*;

public class Main{

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

String name;

System.out.print("First name: ");

name = input.next();

name= name.substring(0, 1).toUpperCase() + name.substring(1).toLowerCase();

System.out.print(name);

}

Explanation:

This declares name as string

String name;

This prompts the user for first name

System.out.print("First name: ");

This gets the name from the user

name = input.next();

This capitalizes the first letter of name and makes the other letters to be in lowercase

name= name.substring(0, 1).toUpperCase() + name.substring(1).toLowerCase();

This prints the formatted name

System.out.print(name);

A computer program is tested by 5 independent tests. If there is an error, these tests will discover it with probabilities 0.1,

Svetllana [295]

Answer:

0.8488

Explanation:

Let E =error found by test 1

Let F=error found by test 2

Let G=error found by test 3

Let H=error found by test 4

Let I= error found by test 5

Given P(E)=0.1, P(F)=0.2, P(G)=0.3, P (H)= 0.4, P (I)=0.5

therefore P(notE)=0.9, P(notF)=0.8, P(notG)=0.7, P(not H)=0.6, P (notI)=0.5

Tests are independent P(not E & not F &not G & not H & not I=P(notE)*P(notF)*P(notG)*P (notH)*P (not I) =0.9*0.8*0.7*0.6*0.5 =0.1512

P(found by at least one test)= 1- P(not found by any test)=1-P(not E& not F & not G & not H & not I ) = 1-0.1512 = 0.8488
