Aclass of 160 students contains 40 honor students, 60 athletes, and 80 who are neither athletes nor honor students.
from the entire group a student is chosen at random.
the fraction equation that proves the events "honor student" and "athlete" are not independent is

answers:
1/8 = 3/32
1/8 = 1/4
1/8 = 3/8
1/8 = 1/2

An oil exploration company currently has two active projects, one in asia and the other in europe. let a be the event that the asian project is successful and b be the event that the european project is successful. suppose that a and b are independent events with p(a) = 0.2 and p(b) = 0.8. (a) if the asian project is not successful, what is the probability that the european project is also not successful? (b) what is the probability that at least one of the two projects will be successful? (c) given that at least one of the two projects is successful, what is the probability that only the asian project is successful? (round your answer to three decimal places.)
