Answer 2

Answer:

1875

Step-by-step explanation:

Given numbers,

1, 2, 3, 4, 5,

∵ Number of ways of choosing first digit of number = 5,

Ways of choosing second digit = 5,

Ways of choosing third digit =  5,

Ways of choosing fourth digit = 5,

Ways of choosing fifth digit = 3 ( because we want an odd number so unit place of the number must be odd, i.e. 1, 3 or 5 )

Hence, the total possible numbers = 5 × 5 × 5 × 5 × 3 = 1875
