In Exercises 15-42, translate each argument into symbolic form. Then determine whether the argument is valid or invalid. You may use a truth table or, if applicable, compare the argument’s symbolic form to a standard valid or invalid form. (You can ignore differences in past, present, and future tense.) If all people obey the law, then no jails are needed. Some people do not obey the law . ∴ Some jails are needed .

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?
Problem #6
A special passcode to unlock your phone consists of 4 digits where repeated digits are not
allowed. If someone were to randomly guess a 4 digit passcode, what is the probability that
they guess your passcode on the first try?
Problem #3
If a card is picked at random from a standard 52-card deck, what is the probability of getting a
black card or a queen?
