Teo has a combonation of quartars, loonies and toonies in his pocket he knows he has 9 coins in total and that he has a least one of each type of coin. a) what is the propobility that Teo has more than $8 b) how many different combonations of coins could Teo use to pay for an item that cost between $10 and $12, if he uses fewer toonies than loonies
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
Counting Theory
The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.
Teo has a combonation of quartars, loonies and toonies in his pocket he knows he has 9 coins in total and that he has a least one of each type of coin.
a) what is the propobility that Teo has more than $8
b) how many different combonations of coins could Teo use to pay for an item that cost between $10 and $12, if he uses fewer toonies than loonies
