The following two way table shows the results of a survey of a high school graduating class. It shows the number of males and females who are continuing their education college and those who have decided to start working instead. If one of the surveyed students is chosen at random, based on the two way table, what is the P (College°)?
your answer as a simplified fraction.

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
