i dont know if this is appropriate or not lol..but its worth a shot right? =/
well i have a math test on monday and i am like CONFUSED and starting to panic. im already not doing well in this class and desperately need a good grade...i know i should have gone to see a school tutor earlier but was so busy with work and all...so i come to you guys =)
the class im taking is finite math and right now we're on probability..
can someone please, if they could, help explain how to work through these problems.
1. Suppose 55% of the students at College own an iPod, 69% own a cell phone, and 35% own both. What is the probability a randomly selected student owns neither item?
2. There are 6 freshmen, 6 sophomores, 8 juniors, and 7 seniors from which to choose a committee of 4 members. What is the probability the committee contains at most 3 freshmen?
if anyone... please.. =( please..thank you..
