sorry
but that is incorrect.
Wikipedia:
The apostrophe ( although often rendered as ' ) is a punctuation mark, and sometimes a diacritic mark, in languages that use the Latin alphabet or certain other alphabets. In English, it serves three purposes:[1]
The marking of the omission of one or more letters (as in the contraction of do not to don't).
The marking of possessive case (as in the cat's whiskers).
The marking as plural of written items that are not words established in English orthography (as in P's and Q's, the late 1950's). (This is considered incorrect by some; see Use in forming certain plurals. The use of the apostrophe to form plurals of proper words, as in apple's, banana's, etc., is universally considered incorrect.)
