What are the prime numbers less than 20?
4. A computer randomly prints a three-digit string of numbers. The string consists only of the digits 0, 1, 2, or 3 and satisfies the extra condition that the sum of its digits is 3. As an example, 021 is one such string. a. Write down the sample space s of all such three-digit strings. (HINT: There should be 10 total outcomes including 021. Make sure you found all of them.)
a. What are all the factors of 200? b. A prime factor is a factor that is also a prime number what are the prime factors of 200? c. Sometimes it is useful to represent a number as the product of prime factors. How could you write 200 as a product using only prime factors?
Writing a number a as product of only prime numbers is called prime factorization d. Tatiana was writing 200 as a product of prime numbers is called. Prime factorization d. Tatiana was writing 200 as a product of prime numbers. She shared with her team the beginning of her work, which is shown.
What process do you think was going through Tatana's mind when she wrote 200 as a product of prime factors? Do you think it matters what products Tatiana wrote in her second step? What if she wrote 10.20 instead? Finish this prime factorization using Tatiana's process.
