Solved 26 We Have Set A 1 2 3 4 5 Using These 5 Chegg Using the digits 1, 2, 3 and 5, how many 4 digit numbers can be formed if a) the first digit must be 1 and repetition of the digits is allowed? b) the first digit must be 1 and repetition of the digits is not allowed? c) the number must be divisible by 2 and repetition is allowed? d) the number must be divisible by 2 and repetition is not allowed?. Thus , we can assign 3 numbers that can be placed on the first three digits and only 1 number on the last digit: p = 3! (1!) p = 3×2×1×1. p = 6 ways. » therefore , there are 6 ways we can form a 4 digit number that is divisible by 2. still have questions?.
Question Chegg Using the digits 1,2,3 and 5, how many 4 digit numbers can be formed if a) the first digit must be 1 and repetition of the digits is allowed? b) the first digit must be 1 and repetition of the digits is not allowed? c) the number must be divisible by 2 and repetion is allowed? d) the number must be divisible by 2 and repetition is not allowed?. Using the digits 1, 2, 3, and 5, how many 4 digit numbers can be formed if: a) the first digit must be 1 and repetition of the digits is not allowed? b) the number must be divisible by 2 and repetition is allowed?. Ncr = n!⁄ ( (n r)! r!) here, n = number of objects in group r = number of objects selected from the group how many 4 digit numbers can be formed using the numbers 1, 2, 3, 4, 5 with digits repeated? solution: repetition of digit is allowed. Solution: we have 4 choices for the first letter, 3 choices for the second letter, 2 choices for the third letter and 1 choice for the fourth letter. hence the number of words is given by 4 × 3 × 2 × 1 = 4! = 24. example 3: how many 2 digit numbers can you make using the digits 1, 2, 3 and 4 without repeating the digits?.

To solve the problem of how many four digit numbers can be formed using the digits 1, 2, 3, 4, and 5 such that at least one digit is repeated, we can follow these steps: step 1: calculate the total number of four digit numbers with repetition allowed. In this case, we have 3 choices for the second digit (2, 3, or 5), 2 choices for the third digit (the remaining two digits), and 1 choice for the fourth digit (the remaining digit). Using the digits 1, 2, 3 and 5, how many 4 digit numbers can be formed if a) the first digit must be 1 and repetition of the digits is allowed? (5 points) b) the first digit must be 1 and repetition of the digits is not allowed? (5 points) your solution’s ready to go!. To solve the problem of how many numbers can be formed from the digits 1, 2, 3, 4, 5 (without repetition) such that the digit at the unit's place is greater than the digit at the ten's place, we can follow these steps: 1. understanding the problem: we need to form numbers using the digits 1, 2, 3, 4, and 5.
