Document Summary

Sta201 class 2: operations on statements and venn diagrams. Ex) rewrite the quote (cid:862)those (cid:449)ho do (cid:374)ot (cid:396)e(cid:373)e(cid:373)(cid:271)e(cid:396) the past a(cid:396)e (cid:272)o(cid:374)de(cid:373)(cid:374)ed to (cid:396)epeat it(cid:863) as a conditional (if ____, then ____) statement. Then construct a truth table for all the possible truth values. If you do not remember the past, then you are condemned to repeat it: p: do remember the past; q: you are condemned to repeat it p. Ex) let p = you are a student in sta201 and q = you attend u of t. both of these statements are. Determine if the converse, inverse, and contrapositive statements are also true. Inverse q p (not p) (not q) (not q) (not p) E(cid:454)) (cid:862)if (cid:455)ou do(cid:374)"t e(cid:454)e(cid:396)(cid:272)ise (cid:396)egula(cid:396)l(cid:455), (cid:455)ou(cid:396) health (cid:449)ill de(cid:272)li(cid:374)e.
