![Learning Target C1 Core: I can use the additive and multiplicative principles and the Principle of Inclusion and
Exclusion to formulate and solve counting problems.
1. A professor is buying breakfast for his students as a way of saying Thank you for a good semester.
Of the students in the class, 22 want cereal for breakfast, 11 want bacon, and 5 want both. How many
students want either cereal or bacon? (remember in this class, 'or' means 'and/or')
2. ITS is assigning all members of the Shocker family a New WSU NewID(tm). It will be in the follow-
ing form A123B456* where the letters are randomly assigned capital English letters, the digits are
randomly assigned 0-9, and the final symbol is from the list {!, *, ?, $, #). How many different ID
numbers can be created?
For example, my NewID is H123B456! and my boss's is X222Y333? (remember the punctuation is
part of it)
3. In the previous question about ID numbers, how many can be created if the letters cannot be repeated
and the digit 0 cannot be used? The punctuation can be repeated.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd375a7e5-ad67-4b21-afad-3fb7503a0e18%2F50f8eab7-6e58-462b-90b4-04eb2e7e851b%2Fr1ivdr_processed.jpeg&w=3840&q=75)
