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 [tex](30-14=16)[/tex]
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=
[tex]\frac{number of possible outcomes}{total number of outcomes}[/tex]
Hence, the probability is : [tex]\frac{16}{30}[/tex] or [tex]\frac{8}{15}[/tex]
If we want this in percentage this is 53.33%.
