- Problem #5 Section A of my math class has 110 students. Section B of my math class has 80 students. a). If I randomly select 15 students from the combined classes, in a way that the order of my selection does not matter, what is the probability that all 15 students can from Section A? b). If I randomly select 15 students from the combined classes, in a way that the order of my selection does not matter, what is the probability that all 15 students can from Section B? c). If I randomly select 15 students from the combined classes, in a way that the order of my selection does not matter, what is the probability that all 7 students come from section A and 8 students come from section B?arrow_forwardProblem #6 A special passcode to unlock your phone consists of 4 digits where repeated digits are not allowed.

- Problem #1 In the 2010 census, it was reported that the United States had a population of 310 million people. Of those, 74 million were under the age of 18. If you chose a person from the U.S. population at random, what is the probability they are under the age of 18? Problem #2 Given a set S={1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, if you were choosing a number at random what is the probability that you would choose an even number or a number larger than 7?arrow_forwardAnswer number twoarrow_forwardAnswer number onearrow_forward
