What does replacement mean in probability?
When the sample is drawn, it is placed back where it was taken from and if subsequent draws are made, it could be selected again.
What is difference between proportion and probability?
Proportion is the probability of a selected sample. probability is the true probability of all cases. If this is not what you are looking for then please specify.

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
