1 answer:

4 0

I 4 - v I < 5

I f(v) I < a

f(v) < a and f(v) > - a

4 - v < 5 and 4 - v > -5

4 - v < 5

v > 4 - 5

v > - 1

4 - v > -5

v < 5 + 4

v < 9

Combine the rangers

-1 < v < 9

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 $\frac{3}{13} \cdot \frac{1}{6} = \boxed{\frac{1}{26}}$ .
