A stock has a return that follows the normal distribution with a mean of $14\%$ and a standard deviation of $7\%.$ What is the probability that the stock will have a return between $14-7\%$ and $14+2*7\%?$ The one$-,$ two$-,$ and three$-$sigma probability of the normal distribution is $68\%,95\%,$ and $99\%.$ Enter a number with one decimal points. Answer the question in percentage terms, i$.$e$.,$ if the answer is $20\%,$ enter $20\mathrm{.}0.$
