A study was conducted that resulted in the following relative frequency histogram. Determine whether or not the histogram indicates that a normal distribution-could be used as a model for the variable. 0.4 0.2 Yo00 2000 3000 4000 5000 Choose the correct answer below. O A. The histogram is bell-shaped, so a normal distribution could be used as a model for the variable. O B. The histogram is not bell-shaped, so a normal distribution could not be used as a model for the variable. OC. The histogram is not bell-shaped, so a normal distribution could be used as a model for the variable. O D. The histogram is bell-shaped, so a normal distribution could not be used as a model for the variable.

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.
