Answer:

The number of pink pens can be 19 .

Total Number of pens = 20

Let x be the number of pink pens

We are supposed to find If the probability of choosing a pink pen is close to 1, how many pink pens would you expect to see in Amanda's bag

Probability of choosing a pink pen = $\frac{\text{Number of pink pens}}{\text{Total Number of pens}}$

Probability of choosing a pink pen = $\frac{x}{20}$

ATQ

$\frac{x}{20}$ ≈1

x≈20

So, the number of pink pens can be 19 .
