8. (i) How many positive integers not exceeding 200 that are divisible by 3 or 5 are there? (ii) What is the minimum number of students, each of whom comes from one of the 50 states, who must be enrolled in a university to guarantee that there are at least 100 who come from the same state?
2. How many positive integers less than 1000 are multiples of 5 or 7? Explain your answer using the inclusion-exclusion principle 3. For the purpose of this problem, a word is an ordered string of 5 lowercase letters from the English alphabet (i.e., the 26 letters from a to z). For example, "alpha" and "zfaxr" are words. A subword of a word is an ordered string that appears as consecutive letters anywhere within the given word. For example, "cat" is...
6. How many times is the digit 3 written when listing all integers from 1 to 1000?
How many 6 digit numbers can be formed if the number formed must be divisible either 5 or 2, AND this number can't begin with a 0, e.x. 0538... is not allowed? What are possible arrangements? ¿Cuántos números de 6 dígitos se pueden formar si el número formado debe ser divisible ya sea 5 o 2, Y este número no puede comenzar con un 0, e.x. 0538 ... no está permitido? ¿Cuáles son los posibles arreglos?
In C program #include<stdio.h> The first 11 prime integers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, and 31. A positive integer between 1 and 1000 (inclusive), other than the first 11 prime integers, is prime if it is not divisible by 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, and 31. Write a program that prompts the user to enter a positive integer between 1 and 1000 (inclusive) and that outputs whether the number...
