Actually, the composition of transpositions should start from right to left.Proof by contrapositive that for x, y ∈ Z, if xy is even then either x or y is even.

- Claim: Most adults would not erase all of their personal information online if they could. A software firm survey of 633randomly selected adults showed that 36% of them would erase all of their personal information online if they could. Complete parts (a) and (b) below. a. Express the original claim in symbolic form. Let the parameter represent the adults that would erase their personal information.We distribute 80 identical pencils in a class consisting of 10 boys and 20 girls in such a way that each of the girls gets at least one pencil but we do not insist on the same thing for the boys. In how many ways can we do this? You do not have to compute the numbers. When writing your answer denote "n choose k" by C(n,k) and do not leave spaces between characters.---Actuarial Mathematicss---
