A school student body has 40% male and 60% female. Six of the students will randomly be chosen for a scholarship.
a) what is the probability of 3 or more males being chosen?
b) what is the expected number of males who are winners?
c) assume students are chosen one at a time - what is the probability that the 4th student chosen will be the 3rd male student chosen?
Pretty stumped with this one... thanks for the help
