Answer:
P(black) = 2/3
Step-by-step explanation:
We need to find the total number of marbles
2 red marbles+ 3 white marbles+ 10 black marbles = 15 marbles
To find the probability that Sam chose a black marble, we take the number of black marbles and divide by the total number of marbles
P(black) = black marbles/total marbles
= 10/15
Divide the top and bottom by 5
= 2/3
Answer:
12
Step-by-step explanation:
Length of one of the boards = 8 feet
Converting to inches
![1\ \text{foot}=12\ \text{inches}\\\Rightarrow 8\ \text{feet}=8\times 12=96\ \text{inches}](https://tex.z-dn.net/?f=1%5C%20%5Ctext%7Bfoot%7D%3D12%5C%20%5Ctext%7Binches%7D%5C%5C%5CRightarrow%208%5C%20%5Ctext%7Bfeet%7D%3D8%5Ctimes%2012%3D96%5C%20%5Ctext%7Binches%7D)
One cut is 16 inches
So, we divide the length of the board by 16
![\dfrac{96}{16}=6](https://tex.z-dn.net/?f=%5Cdfrac%7B96%7D%7B16%7D%3D6)
So, one board is cut into 6 pieces.
The other board is also 8 feet long.
So, the number of pieces the other board is cut into is also 6.
Hence, a total of
pieces of each 16 inches long can be cut from the two boards.
