Marta_Voda [28]

Answer:

The number of pink pens can be 19 .

Step-by-step explanation:

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 .

Blizzard [7]

Answer:

Hence,

Total purchase cost of windows alone :

5323.50 - 2100 = 3,223.50

Therefore, the number of windows purchased is :
