Determine if the events are independent or dependent (by using logic). Getting a raise in salary, and buying a new home. a) b) Having a large neck size and having a high IQ. c) Having a low resting heart rate and exercising frequently.
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.
a)
Event A = Getting raise in salary
Event B = Buying a new home
Event A and B are Dependent.
Because, If salary will increase then the ability to buy a home is also increase.
