If there are 2,000 females and 2,000 males enrolled at a college and four different students are randomly selected to receive a book scholarship, what is the probability that at least one is female? Calculate the probability two ways: a) treat as dependent selections and b) treat as independent selections.

500

Step-by-step explanation:

you just divide 2000 by 4 and get 500

1/800 is the right answer

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
