9 Liza has the following shirts in her closet.
• 3 red shirts
4 blue shirts
3 yellow shirts
1 purple shirt
• 1 black shirt
Liza will randomly choose one shirt. Then she will put it back and randomly choose another shirt. What is the probability that she
will choose a red shirt and then a yellow shirt?

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.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
