can somebody help me to know the proper way to solve this kind of problem.(adsbygoogle = window.adsbygoogle || []).push({});

correct answers are as follows, 6/10 or (36/60) , 4/10 , 3/5Code (Text):Five employees of a firm are ranked from 1 to 5

based on their ability to program a computer.

Three of these employees are selected to fill

equivalent programming jobs. If all possible

choices of three (out of the five) are equally

likely, find the following probabilities

a The employee ranked number 1 is selected.

b The highest-ranked employee among those

selected has rank 2 or lower.

c The employees ranked 4 and 5 are selected.

the formula for probability is s/n ; where n is the total number of outcomes. I know how to get n by using 5P3 (5 ways taking 3 at a time). now, how do i get s (success outcome)? that confuses me. (I know that s(success outcome) is the number that will lock / target your condition) Thank you
