Two Smallest (20 points). Write a program TwoSmallest.java that takes a set of double command-line arguments and prints the smal

Ivan

Answer:

Written in Java

import java.util.*;

public class Main {

public static void main(String args[]) {

int n;

Scanner input = new Scanner(System.in);

n = input.nextInt();

double nums []= new double [n];

for (int i=0; i<n;i++)

{

nums[i] = input.nextDouble();

}

Arrays.sort(nums);

System.out.println("The two smallest are: ");

for (int i=0; i<2;i++)

{

System.out.println(nums[i]);

}

Explanation:

This line declares number of input

int n;

This line calls the Scanner function

Scanner input = new Scanner(System.in);

This line gets input from user

n = input.nextInt();

This line declares an array of n elements

double nums []= new double [n];

The following iteration gets input into the array

for (int i=0; i<n;i++)

{

nums[i] = input.nextDouble();

}

This line sorts the array

Arrays.sort(nums);

The following iteration prints the two smallest

System.out.println("The two smallest are: ");

for (int i=0; i<2;i++)

{

System.out.println(nums[i]);

}

A bowl contains 20 candies; 15 are chocolate and 5 are vanilla. You select 5 at random. What is the probability that all 5 are c

Sindrei [870]

Answer: 0.1937

Explanation:

Given : A bowl contains 20 candies; 15 are chocolate and 5 are vanilla.

If we select 5 candies, then the number of ways to select them is given by permutations.

The number of ways to select 5 candies is given by :-

$^{15}P_5=\dfrac{15!}{(15-5)!}=\dfrac{15\times14\times13\times12\times11\times10!}{10!}=360360$

The number of ways of selecting any 5 candies out of 20:-

$^{20}P_5=\dfrac{20!}{(20-5)!}\\\\=\dfrac{20\times19\times18\times17\times16\times15!}{15!}\\\\=1860480$

Now, the probability that all 5 are chocolate :-

$=\dfrac{360360}{1860480}=0.193691950464\approx0.1937$

Hence, the probability that all 5 are chocolate =0.1937
