Kyle has three short straws, four medium straws, and six long straws. If he randomly draws two straws, one at a time without rep

ipn [44]

Before the first straw is drawn, there are three short straws and $3+4+6=13$ straws in all. Thus, the probability of drawing a short straw first is $\frac{3}{13}$ .

After a short straw is drawn, there are two short straws and twelve total straws, a probability of $\frac{2}{12} = \frac{1}{6}$ .

Thus, the probability of both of these events occurring is $\frac{3}{13} \cdot \frac{1}{6} = \boxed{\frac{1}{26}}$ .

I would just subtract 9.35 from 30.5 so you would get 21.15. This means he pays $21.15 for the jacket.
