Question

Amanda's book bag is 0.10. Some of Amanda's pens are removed and replaced with pink pens. Her book bag still contains a total of 20 pens. 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?

Answer 1

The number of pink pens can be 19 .

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 =
`(x)/(20)`

ATQ

`(x)/(20)`≈1

x≈20

So, the number of pink pens can be 19 .
