Answer :
Final answer:
The probability of Amanda randomly choosing a purple pen from her book bag is 50%. Since there are no black pens in Amanda's book bag, the probability of drawing a black pen is 0%.
Explanation:
The question deals with basic probability concepts. If Amanda's book bag contains pens of just three colors and the probabilities of selecting a blue pen and a green pen are 40% and 10%, respectively, then the probability of choosing a purple pen must be the remaining percentage. Since the total probability for any event must equal 100%, we calculate the probability for the purple pen as:
100% - Probability(Blue) - Probability(Green) = 100% - 40% - 10% = 50%
Therefore, the probability of Amanda randomly choosing a purple pen from her book bag is 50%.
For Part B, since Amanda's book bag only contains blue, green, and purple pens, the probability of drawing a black pen is 0%. It is not possible to draw a pen color that is not already in the book bag.
