To find how many odd numbers less than 1000 can be formed using the digits 0, 2, 5, and 7 (with repetitions allowed), we will consider the numbers based on their digit count: one-digit, two-digit, and three-digit numbers.Step 1: Count O
B={x:x is an odd natural number and x<15} The odd natural numbers less than 15 are:B={1,3,5,7,9,11,13} Step 3: Find the Union of Sets A and BThe union of two sets A and B is the set of elements that are in either A or B (or both). We will combine the elements ...

Theodd numbers formulais expressed as 2n ± 1, where, n ∈ W (whole numbers). We know that an odd number is always expressed as 1 less or more than an even number. An even number is expressed as 2n, where n is a whole number. Therefore, the formula for odd numbers is expressed ...

解析 There are 400 odd numbers between 200 and 1000. and there are 100 multiples of 5 less than 500 (including zero). But the two cases overlap-from 200 to 500 there are 30 odd numbers that are multiples of 5. Hence Total = 400 + 100 - 30 = 470. ...
Even numbers less than 10 can be listed as 2, 4, 6, and 8. These numbers are completely divisible by 2 without anyremainder. What are Even Composite Numbers? Even numbers are those numbers that are completely divisible by 2. For example, 2, 4, 6, 8, 10, and so on are even number...
