A student has to take 4 of the following 7 classes before they are allowed to graduate chemistry, biology, physics, economics, computer
science, theatre, and thetoric. How many ways can a student choose 4 classes? When looking at random selection what is the probability that a
student's choice will not have included physies?

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

34

step-by-step explanation:

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.
