Solution The correct option is B (i) 60, (ii) 108(i) When repetition of digits is not allowed: Since we have to form a 3-digit odd number, thus the digit at unit's place must be odd. Hence, the unit's place can be filled up by 1, 3 or 5, that is, in 3 ways. Now, the ten's digit can be filled up by any of the remaining 5 digits in 5 ways and then the hundred's place can be filled up by the remaining 4 digits in 4 ways. Hence, the number of 3-digit odd numbers that can be formed =3×4×5=60. (ii) When repetition of digits is allowed: Again, the unit's place can be filled up by 1, 3, 5. that is, in 3 ways. But the ten's and hundred's place can be filled up by any of the 6 given digits in 6 ways each. (since repetition is allowed) Hence, the number of 3-digit odd numbers that can be formed =3×6×6=108.In mathematics, permutation is known as the process of arranging a set in which all the members of a set are arranged into some series or order. The process of permuting is known as the rearranging of its components if the set is already arranged. Permutations take place, in more or less important ways, in almost every area of mathematics. They frequently appear when different commands on certain finite sets are considered. Nội dung chính Show

What is a Combination? A combination is an act of choosing items from a group, such that (not like permutation) the order of choice does not matter. In smaller cases, it is possible to count the number of combinations. Combination refers to the union of n things taken k at a time without repetition. In combination, you can select the items in any order. To those combinations in which re-occurrence is allowed, the terms k-selection or k-combination with replication are frequently used. Permutation Formula In permutation r things are selected from a set of n things without any replacement. In this order of selection matter.
Combination Formula In combination r things are selected from a set of n things and where the order of selection does not matter.

How many 5 digit even numbers with distinct digits can be formed using the digits 3 4 7 78?Therefore, there will be 60 distinct 5 - digit numbers. Was this answer helpful? How many 5 digit even numbers with distinct digits can be formed using the digits?Case 1: If 0 is filled in units place then the number of ways = 5 × 6 × 6 × 6 × 1 = 1,080 ways. Case 2: If 0 is not filled in units place then the number of ways = 5 × 6 × 6 × 6 × 2 = 10 × 216 = 2,160. Total number of ways = 1,080 + 2,160 = 3,240. How many 5 digit numbers are there with distinct digits can be formed using the digits 1,2 5 5 4?Answer. Step-by-step explanation: 36 is the digital even number with distinct digit can be formed using the digit 1,2,5,5,4. How many different 5 digit even numbers can be formed?The question was, how many 5 digit even numbers can be made if repetition is not allowed and the number four must be included. the answer is 7686. How many odd numbers of 5 digits can be formed using all the digits from 0 to 9 if repetition of digits is allowed?∴ The required result will be 192. How many 5 digit even numbers with distinct digits can be formed using the digits?Answer & Solution The 5 digit even numbers can be formed out of 1, 2, 5, 5, 4 by using either 2 or 4 in the unit's place. This can be done in 2 ways. Corresponding to each such arrangement, the remaining 4 places can be filled up by any of the remaining four digits in 4! / 2! = 12 ways. How many number of five digits can be formed with the digits 0 1,2 3 4 without repeating a digit?∴ Total number of 5–digit numbers that can be formed using the digits 0, 1, 2, 3, 4 = 5! – 4! = 120 – 24 = 96. How many 5 digit numbers can be formed with exactly two distinct digits?The total is 9⋅9⋅15=1215. How many 3 digit odd numbers with distinct digits are there?Thus there are 60, 3 digit numbers, with distinct digits, with each of the digits odd. Note: We should be very careful about multiplying those numbers. How many 3 digit odd numbers can be formed using the digits 0 1 2 3 4 and 5 if I repetition of digits is allowed II Repeation of digits are not allowed?Hence, the number of 3-digit odd numbers that can be formed =3×6×6=108. How many three digit odd numbers can be formed using the digits 1 2 4 and 6 if repetition of digits is not allowed?
How many 3 digit numbers can be formed from the digits 1 2 3 4 and 5 how many different 3 digit odd numbers can be formed?How many 3-digit numbers can be formed from the digits 1, 2, 3, 4 and 5 assuming that repetition of the digits is not allowed. = m x n x p = 5 x 4 x 3 = 60. How many 3Thus, The total number of 3-digit numbers that can be formed = 5×4×3 = 60.
How many 3So, it can be filled in 6 ways.
Hence, by the fundamental principle of multiplication, the required number of odd numbers `= (3xx6xx6) = 108. ` Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. How many three digit odd numbers can be formed using the digits 1 2 4 and 6 if repetition of digits is not allowed?But the ten's and hundred's place can be filled up by any of the 6 given digits in 6 ways each. Hence, the number of 3-digit odd numbers that can be formed =`3xx6xx6=108. How many four digit odd number can be formed using the digits 12345 without repetition?=24 permutations of the 4 digits.
