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

To calculate the probability of pulling out a marker, we need to divide the number of markers by the total number of writing implements in the backpack. In this case, the number of markers is 3 and the total number of writing implements is 2 (lápices) + 5 (bolígrafros) + 3 (marcadores) = 10. Therefore, the probability of pulling out a marker is:
3 (number of markers) / 10 (total number of writing implements) = 0.3 or 30%
So, the correct answer is option c. 30%.
Hope this helps! Let me know if you have any other questions.
