| A. Yes, the table shows a probability distribution. | B. No, the random variable x's number values are not associated with probabilities. | C. No, the random variable x is categorical instead of numerical. | D. No, not every probability is between 0 and 1 inclusive. |E. No, the sum of all the probabilities is not equal to 1. nd the mean of the random variable x. Select the correct choice below and, if necessary, fill n the answer box to complete your choice. A. u= women (Round to one decimal place as needed.) O B. The table does not show a probability distribution. nd the standard deviation of the random variable x. Select the correct choice below and, if necessary, fill in the answer box to complete your ch DA. G= women (Round to one decimal place as needed.) B. The table does not showa probability distribution.
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.
