first you have to keep in mind that probability is # of favorable outcomes/ # of possible outcomes. we already know (given that no two students are the same height) that there is only 1 possible way to order the students from shortest to tallest therefore, we have established that we have 1/# of possible outcomes. to find the number of possible outcomes you take 8 factorial. 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 40320. now you have the # of favorable over # of possible = 1/40320 = .0000248015873 = 2.48015873 E-5.

Given eight students four of which are females if two students are selected at random without replacement what is the probability that both students are female?
The probability of selecting 1 female at random is 4/8 There are now 7 students, 3 of which are female so the probability of selecting another female is 3/7 The probability two randomly selected students are female is (4/8)x(3/7)= 3/14
What is the probability a girl is chosen if 15 students are girls and 10 students are boys?
The ratio of girls to total students is 15:25, or 3:5. Three out of five students are girls so there would be a 60% probability that a girl would be chosen; a 2 out of 5 chance, or 40% probability that a boy would be chosen.
