You may want to read Permutations and Combinations and combinatorics before doing this worksheet. Note that I originally wrote this worksheet for a Canadian audience; a "loonie" is a $1 coin and a "toonie" is a $2 coin. "Lottario" was a lottery that was held in Ontario at the time.
- A penny, a nickel, a dime, a quarter, a loonie, and a toonie are
flipped. How many possible outcomes are there?
- How many three-digit numbers are there such that all three digits
are divisible by three?
- Calculate the number of arrangements of the letters of the word
- All combinations are valid.
- The two M's are side-by-side.
- All of the vowels are at the start of the arrangement.
- In how many ways can three cards be selected at random from a
deck of cards?
- In Lottario, six numbers are drawn from a pool of 45. How many
different combinations of six winning numbers are there?
- How many five-person committees can be selected from six men
and eight women if there must be at least two women included?
