(b) What is the probability an indlvidual large-cap domestic stock fund had a three-year return of \( 10 \% \) or less? (Round your answer to four decimal places.) (c) How big does the return have to be to put a domestic stock fund in the top \( 15 \% \) for the three-year period? (Round your answer to two decimal places.)
