Answer:
The value of the experimental probability is greater
Step-by-step explanation:
For the theoretical probability;
the probability that a card with the number 3 is selected is 1/5
We consider that the probabilities of each selection are equal, for the theoretical probability
For the experimental, we simply place the frequency of the selection 3 over the total
that will be 128/400 = 8/25
As we know that 8/25 is greater than 1/5
We can conclude that the value of the experimental probability is greater than that of the theoretical
Answer:
12.54 square miles
Step-by-step explanation:
Area of Parallelogram = Base x Height
In this case, Base = 3.3 mi and Height = 3.8 mi
Hence,
Area = 3.3 x 3.8 = 12.54 square miles
