Let's see. The word is "strawberry." I need to find out how many times the letter "r" appears in it. Okay, so I'll look at each letter in the word one by one. First letter: s - that's not r. Second letter: t - no, not r. Third letter: r - yes, that's an r. Fourth letter: a - not r. Fifth letter: w - not r. Sixth letter: b - no. Seventh letter: e - not r. Eighth letter: r - another r. Ninth letter: y - not r. So, I found two r's in "strawberry." Let me just double-check to make sure I didn't miss any. Starting over: s, t, r, a, w, b, e, r, y. Yes, the third letter is r, and the eighth letter is r. That's two r's. Wait a minute, is there another r hidden somewhere? Let's see. s t r a w b e r y. No, that's all. Just two r's. I think that's correct. *Final Answer* \[ \boxed{2} \]
