Answer :
Final answer:
When some pens in Amanda's bag are replaced with pink pens until the probability of drawing a pink pen is 'close to 1', it implies there are nearly all pink pens in the bag. Considering 'close to 1' as 95% (or 0.95) and given the total number of pens as 20, it is estimated that there would be around 19 pink pens.
Explanation:
In this scenario, we are talking about the probability of randomly choosing pens of different colors from Amanda's bag. Initially, the probability of randomly choosing a blue pen is 40% and a green pen is 10% (or 0.10 when expressed as a decimal). When some pens are replaced with pink pens until the probability of drawing a pink pen is 'close to 1', it implies that the majority of the pens are pink. Since we're given that the total number of pens in the bag remains 20, you would expect nearly all of those pens to be pink. 'Close to 1' isn't an exact number, but if we consider it to be 95% (or 0.95), for example, we could multiply 0.95 by 20 to estimate that there would be around 19 pink pens in the bag.
