Question

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

Answer 1

Add the number of writing implements. That number is 100%.

Answer 2

pr(marcadores)=3/10
pr(bolígrafros)=5/10
pr(lápices)=2/10

Answer 3

How can 3/10 = 100%?

-MC

Answer 4

3/10 cannot be 100%. Lily is mistaken.

Answer 5

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).
