Answer: The required probability is [tex]\dfrac{8}{125}[/tex]
Step-by-step explanation:
Since we have given that
Number of spruce tree = 20
Number of maple tree = 50
Total trees = 70
We need to find the experimental probability that the next tree Colleen to get a spruce tree.
So, the probability would be :
[tex](\dfrac{20}{50})^3=(\dfrac{2}{5})^3=\dfrac{8}{125}[/tex]
Hence, the required probability is [tex]\dfrac{8}{125}[/tex]
