\(e\): Nigel is exercising regularly,

\(f\): Nigel is getting fitter.

(a) Write down the following statement in words.

$$f\Rightarrow e$$(b) Write down, in words, the contrapositive statement of \(f\Rightarrow e\).

(c) Determine whether your statement in part (a) is logically equivalent to your statement in part (b). Justify your answer.
