Suppose the population average amount of dog biscuits in a bag is 40 pounds with a standard deviation of 6 pounds. A simple random sample of 64 bags is selected. Round probability answers to 4 decimal places, i.e. XXXX DO NOT include leading or ending zeros.
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.
