Need help with this activity:
Imagine that in your backpack you have several writing implements, all of which are the same size: 2 lápices, 5 bolígrafros, 3 marcadores. If you pull one out at random, what is the percent probability that it will be a marker?
a. 20%
b. 50%
c. 30%
d. 100%
C?
Thanks

Add the number of writing implements. That number is 100%.
pr(marcadores)=3/10
pr(bolígrafros)=5/10
pr(lápices)=2/10
How can 3/10 = 100%?
-MC
3/10 cannot be 100%. Lily is mistaken.
What Lily meant to say was that if you add ALL the markers: 2 + 5 + 3 you get 10, which is 100% of the markers she has (total).

To determine the percentage probability of pulling out a marker from your backpack, you need to know the total number of writing implements you have as well as the number of markers you have.
First, calculate the total number of writing implements you have:
2 pencils + 5 pens + 3 markers = 10 writing implements
Next, calculate the number of markers you have:
3 markers
Finally, divide the number of markers by the total number of writing implements and multiply by 100 to get the percentage probability:
(3 markers / 10 writing implements) * 100 = 30%
So, the correct answer is c) 30%.
