This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to cor part. Tutorial Exercise Determine whether the geometric series is convergent or divergent. If it is convergent, find its sum. 10 + 5 + 2.5 + 1.25 + ... Step 1 To see 10 + 5 + 2.5 + 1.25 + ... as a geometric series, we must express it as The ratio arn + 1 of any two successive terms in the geometric series arn arn is n = 0 Submit Skip (you cannot come back)
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.
