Answer :
Final answer:
The probability of Amanda randomly choosing a purple pen from her book bag is 50%, calculated by subtracting the given probabilities for blue and green pens from 100%.
Explanation:
The question asks us to find the probability of Amanda randomly choosing a purple pen from her book bag, given that the probability of choosing a blue pen is 40% and the probability of choosing a green pen is 10%. In probability theory, all possible outcomes in a sample space must add up to 100%. Since we already have the probabilities for blue and green pens, we can calculate the probability of choosing a purple pen by subtracting the probabilities of the other two pens from 100%.
To calculate, we use the following steps:
- Add the probabilities of choosing a blue pen and a green pen: 40% + 10% = 50%.
- Since the total probability must equal 100%, subtract the sum obtained in step 1 from 100% to find the probability of choosing a purple pen: 100% - 50% = 50%.
Therefore, the probability of Amanda choosing a purple pen from her book bag is 50%.
