Answer:
The probability is 53.33%.
Step-by-step explanation:
A model builder has 30 pieces of balsa wood in a box.
4 pieces are 15 inches long.
10 pieces are 12 inches long.
Says rest are 8 inches. So, rest are ![(30-14=16)](https://tex.z-dn.net/?f=%2830-14%3D16%29)
16 pieces are 8 inches long.
Now, we have to tell the probability the builder will pull an 8-inch piece from the box without looking.
The probability is given by=
![\frac{number of possible outcomes}{total number of outcomes}](https://tex.z-dn.net/?f=%5Cfrac%7Bnumber%20of%20possible%20outcomes%7D%7Btotal%20number%20of%20outcomes%7D)
Hence, the probability is :
or ![\frac{8}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B15%7D)
If we want this in percentage this is 53.33%.
