Cole Publisher:McDougal Littell College Algebra ISBN:9781337282291 Author:Ron Larson Publisher:Cengage Learning How many 2∴ 9 possible two-digit numbers can be formed.
How many 2Let's form the two-digit numbers using the digits 3, 7, and 9 if the repetition of the digit is allowed. Therefore, the two-digit numbers formed by using the digits 3, 7, and 9 are 33, 37, 39, 73, 77, 79, 93, 97, and 99.
How many two digit numbers can be formed from the digits 1 2 3 4 and 5 if repetitions are allowed?∴ The number of 2-digit numbers formed from the given set with repetition =5P2+5=20+5=25.
How many 2Explanation: We have four digits 1,2,3,4. The first digit can be any of these four digits. Now we have already chosen the first digit.
