5. Given two conditions P and Q, there are four ways in which they might be related to each other. •P is necessary but not sufficient for Q. •P is sufficient but not necessary for Q. •P is both necessary and sufficient for Q. •P is neither necessary nor sufficient for Q. For each problem below, do the following: i. Determine whether P is necessary, sufficient, both necessary and sufficient, or neither necessary nor sufficient for Q. ii. Justify your answer to i). iii. Write the symbolic notation for the implication, if any. a) P="each side is equal in length to each of the others", Q = "it is a square" b) P="the person is a younger sibling", Q = "the person has an older sibling" c) P="it is a triangle", Q = “it has three sides"
