Given that just 17 of the 66 vials in the shipment do not exhibit hairline fractures likelihood of lacking hairline cracks = 17 / 61

If you randomly select 2 vials from the shipment

(Probability of not having a hairline cracks)' = <u> 17-1  </u>

                                                                            61-1

= 16 / 60

There are possible methods to choose two vials at random. 68C2 = 2278.

how many methods there are to choose two vials at random and ensure that none of them have a hairline crack = 16C2 = 120.

Thus, there are a total of 2 vials that may be chosen at random from which at least 1 has a hairline crack.

2278 - 120

= 2158

aniked [119]

Answer:

A Metaphor

Explanation:

A metaphor is a comparison between two unlike things without using like or as. There is no like or as in this poem to make the comparison between the narrator and a stairway. In the poem she says, "Life for me ain't been no crystal stair". She compares her life to a stairway. She describes the stairway as having things like tacks, splinters, and torn up boards. These are metaphors for the obstacles she had to overcome in her life.
