ci. Betty and John roll a die. If the result is a 1 or 2, John wins; otherwise Betty wins. What is the event John wins? ii. How many events are there associated with the roll of one die? d. A die is thrown. Represent the following events in a Venn diagram. A: An odd number is thrown. B: A number less than 5 is thrown. C: A number divisible by 3 is thrown.
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.
