<image> In a class of $$50$$ students, the results of a 100-meter test are all between $$13$$ seconds and $$18$$ seconds. The test results are divided into five groups: the first group $$[13,14)$$; the second group $$[14,15)$$, $$…$$, the fifth group $$[17,18]$$. The frequency distribution histogram obtained using the above grouping method is shown in the figure. If the grades are considered good when they are greater than or equal to $$14$$ seconds and less than $$16$$ seconds, then the number of students in the class with good results in this 100-meter test is ______ .
