Question

a bag contains 9 purple erasers, 18 orange erasers, and 9 pink erasers. morgan selects an eraser from the bag without looking. determine if selecting each color is impossible, unlikely, as likely as not, or likely.
options (with audio icons):

• impossible: green
• unlikely: pink
• as likely as not: orange
• likely: orange or pink
• (left side with audio icon): not pink

Explanation:

Step1: Calculate total erasers

Total erasers = $9 + 18 + 9 = 36$

Step2: Analyze green selection

No green erasers exist.
Probability: $\frac{0}{36} = 0$

Step3: Analyze pink selection

Pink erasers = 9.
Probability: $\frac{9}{36} = \frac{1}{4}$

Step4: Analyze orange selection

Orange erasers = 18.
Probability: $\frac{18}{36} = \frac{1}{2}$

Step5: Analyze orange or pink selection

Orange + pink = $18 + 9 = 27$.
Probability: $\frac{27}{36} = \frac{3}{4}$

Step6: Analyze "not pink" selection

Non-pink erasers = $9 + 18 = 27$.
Probability: $\frac{27}{36} = \frac{3}{4}$

Answer:

• green → Impossible
• pink → Unlikely
• orange → As Likely as Not
• orange or pink → Likely
• not pink → Likely
